Vanessa Amorosi & Guy Sebastian - Crazy + I Will Survive (Live at Perth Telethon 2009) 

friggen awesome...Guy is simply the best and I tell you, Vanessa is out of this world too.....

That was just crazy good, this was my first time hearing Vanessa Amorosi, I guess this is probably the beginning of going down the rabbit hole 👍

I love Guy Sebastian ...his voice is amazing

Omg never expecting this duo. Guy is a beast!!

Love love seeing them sing together.

MY GUY IS BACK I LOVE ❤ EVERY THING YOU SING ❤ YOU 2 ROCK THIS SONG 🎵

Love ‘‘em both - Australian Talent!

Vanessa is in a lane of her own 👏👏👏👏 Bravo

2 awesome voices

🔥🔥

I never knew how much alike Rhonda Burchmore and Vanessa were.

Vanessa should now reinvent herself as Australia’s diva bringing back the smooth ballads, there is no woman diva but Vanessa that can pull off this feat. Australia does not have a female vocalist like Vanessa! Bring back the smooth Vanessa!

@ThatSingerReactions Here is one for you :)

I don't remember this at all... very odd.

Guy taking on Vanessa in a vocal showdown - bad idea!
