Will.I.Am and Leah performs 'Bang Bang' - Live Final | The Voice UK - BBC 

I watched all "The voices" all over the world since start + kids versions. There is no bigger robbery in the history of the show than Leah not winning

Leah's the most versatile and has the best control of her voice while Will is the most creative of the coaches. Great combination, resulting to a masterpiece!

Well Will I am may not be the best singer, rapper whatever he does. But my god he sure is creative

i cant stop watching this. her voice is perfect for this song.

3 years on and this is still the best performance on any talent show ever. Leah was the most exciting artist ever found on The Voice - how she's not lighting up the music world is a total mystery to me.

This should have been released instead of the actual version Will released

Better than the original

tfw when its been 7 years and you're still listening to this song

7 years later, 2021 and I still love this performance.

I can literally watch this over and over and over again!!

this is one of the greatest things I have ever watched!

Still occasionally watching this ten years on. Leah was such immensely talented fun! I hope that she is happy and doing well.

how she didn't win is beyond me!! This chick Leah is amazing!!!

best fucking duet ever and better than the album one xD

this song suited her voice well i feel

People questioning whether will was the right choice for her lol. 100%. Will.i.am knew she was special and after the show he signed her up and he helped her make an Album that will release this year. If she chose any other judge and she lost I dont think they would of signed her up. Just the standard "keep trying". Will.i.am said he'd do everything in his power to make sure as many people as possible heard her and help her reach as far as she can. And the thing i've learned about will.i.am is that when he promises something, he does it. He may not be everyones cup of tea but when he has something special in his hands he knows how to nature it to its best potential.

The real winner and the best coach

She sings just like in the 60s. I love her. I wish we could go back to that era and correct the mistakes of today.

2022 and im still watching this magnificent show.Just amazing

I cant stop watching this. Can't wait to hear Leahs album, especially if its produced by Will.I.Am.

I’ll never forget this! She had such a unique voice

her voice is so special, I can't get enough of it

1:59 her face when Will puts his hand on her shoulder. I laughed a bit harder than I should've...

8 years ago? I remember this like it was yesterday

When you're s far in 2015 you thought it was bang bang by Jessie j

I just loved their rapport with each other. Most people would feel so intimated in front of someone of his caliber, but not Leah. She is very confident in her talent/gift.

Better than the original. I watch this at least once a week and repeatedly when I do. I can't get enough of it. Song of the year, performance of the year... LEGENDS, both of them!

Y didt she win any way the best moment of the voice so far ! #teamwill

is it just me or does the backround look a bit gatsby-ish? it's great!

the best version of bang bang

Her and this song is perfect 😱 CANT STOP WATCHING ❤️❤️❤️👌

Will please record this song with Leah!!!

I think this was just amazing. That performance was so different. The way they pitched Wills Voice gave so much attention to Leahs voice. This was awesome!

The choice was absolutly right!!!! People are so narrow-minded that's crazy, the song was awesome for her voice

I remember watching this and thinking this is the best thing iv ever watched!

God she KILLED it!!! Before I knew this was a judge/contestant duet, I thought she was some other famous singer up there with Will.i.am. I LOVE this girl. LOVE her eyes, her lips, and her personality. Oh and her adorable accent.

*MOST GENIUS COLLAB EVER!!!!!!!* pls tell me she won??!!!!

I love the way Leah used this song. She didn't play with it too much, but she let her voice go in different regions throughout the song. She should have won, but the pity votes got Andrea and I think you are all stupid cause I voted for Leah, thank you very much. Just like Will, I know talent when I see it- but unlike you,

10 years on, best singer ever on the voice.

will.i.am is so intelligent when it comes to spotting talent. he has the ability to know a winner very quickly .he understands the music industry so well. he jokes and makes funny comments but make no mistake he is one very switched on guy

2020 and this is still one of the most creative Voice performances ever! Perfect!

I think what we've learned from all these talent shows is that they aren't really interested in talent.

I always come back to this version

I still cannot get enough of this performance. It was incredible.

I still remember this performance and I had to look it up. So glad I found it! The best I have ever seen on The Voice

She is so amazing!

I was 8 when I first saw this, I see this on my recommended and immediately remembered it - what a great performance!

here I come again and this time i was crying because i felt so happy watching it. THE BEST.

what a voice she get!!!! she should have wun!

I want her to be HUGE in the industry!

Will is so creative and blessed musican. I love his sound and performance!!

Wish Leah had a larger part in the song, she deserved to win

At first I thought excellent.Now I can't get it out of my mind.Masterpiece!!!Greetings from Cuba.

This performance was what we call A SHOW.

This chick is totally awesome!!....you didnt win the voice but you were the winner in my book...hope u blowin up chica!

2019 anyone?? 👑👑

I wish this version of bang bang was on spotify

watching this live was the last time i felt happiness

Still watching in 2023. This is so much fun. Her versatility and Will's creative genius are fabulous. Where is Leah now?

Will i am’s dancing was excellent And some beat when it drops

go girl kick it whatttta a voice my gosh

This is such a mesmerizing performance! Totally love it! She should have won.

I watched her on the voice when I was 9 and she was my favourite from the beginning I still love her so much

Never knew Wills talent till this video, what a guy. Best duo will and leah

one of the best performances to date. killer song, banging beat. rock stars, all of them performing that

Phenomenal vocal delivery but, also, hats off to every single performer in that set. That performance was polished pretty much to music video quality and it wouldn't have worked if even one of them had been off.

This remains my fav collab between coach and artist on the Voice

Now that's party. William has such a swag! Mam

It's truly one of the best performance in The voice !

her voice is so i dont know i have no words its fckn awesome this bang bang bang wow my heart to much awesomeness for me D;

Elle est tout simplement époustouflante! Un vrai trésor cette fille!

What an awesome production number! One of the best ever I’ve seen on The Voice!

this version honestly is better, mooooorrrrreeeeee better than the original........ Leah's unique voice making this song live

2016 - still the best Voice performance ever.

her voice has no boundaries! she is amazing! she must get e record deal!

I love this so much when we were in a market in Phuket, Thailand last year I asked the bar tender to play it and told him his bar which was empty would fill up if he played it. He did and within seconds his bar was crowded, pulling power of a really good track and Will is Brill -I-ant!

I find Leah so attractive in the weirdest way lol idk what it is about her, amazing performance tho

Leah I love her style of singing she’s super amazing her voice is very unique

Gifted vocals, an already seemingly seasoned stage presence, swag, PURE AMAZING TALENT! I'm truly exited to see what this girl has in store for us.. if she's singing I'm in! She's TOO GOOD TO JUST BE TASTING THE LIMELIGHT!

This is the best version of this song I ABSOLUTELY LOVE THIS !!!!

Will.I.am is so so talented... #speechless

Her voice during this performance sounds like britney's voice.

this was most certainly the best of the best of voice uk!!!!!!!!!!!!!!!!!!!!!!!!well done leha

this was one of the best performances I've ever seen. SO WELL PUT TOGETHER! And will goes in with the dancing 🌟

OMG their voices are perfect for this song everything sounds perfect also I never knew that will could tap dance

She really should have won last year with that performance awesome work by both artists

6 años después, sigue siendo una de las mejores presentaciones de todas las temporadas ❤️

Love love love this can not get.enough! Leah has an amazing voice

Love this. So talented, BOTH of them.

Her voice fits the song so well

My favourite performance of all the time all around world. April 2018

Leah & Vince Kidd need a song together!!! Epic :)!!!

Still dont understand how she didnt have insane success in the industry after this show

this is freaking amazing. . I love this guy, he's got the best ideas. I honestly thought this girl couldn't sing that well, but her charisma and passion with the way Will managed her makes me want to buy her album.

The Music of her was so great and Wills Show also, they fit perfectly as Team.

The best performance on The Voice UK, she truly is pure talent

will is such an incredible performer ❤️

absolutely A-MA-ZING!!!

I LOOOOOOOVE everything about this video. I can't stop watching it lol o m g. I'm so late 😂😂

The best performance I've ever seen. Especcialy on the Voice.
