Glee Cast - Firework (karaoke version) 

Thank you, GleeOriginalKaraoke - / gleeoriginalkaraoke
Firework by Katy Perry is featured in Silly Love Songs, the twelfth episode of Season Two. It is sung by Rachel. The Glee Club's assignment was to sing a love song to a partner, and Rachel uses Finn as her inspiration after he comes down with mononucleosis and admits to her that when he kissed Quinn, he experienced 'fireworks'.
LYRICS:
Rachel:
Do you ever feel like a plastic bag, drifting through the wind, wanting to start again?
Do you ever feel, feel so paper thin?
Like a house of cards, one blow from caving in?
Do you ever feel already buried deep?
6 feet under screams but no one seems to hear a thing.
Do you know that there's still a chance for you
'Cause there's a spark in you
You just gotta ignite, the light, and let it shine
Just own the night like the 4th of July
'Cause baby you're a firework
Come on, show 'em what you're worth
Make 'em go "Oh, oh, oh"
As you shoot across the sky-y-y
Baby, you're a firework
Come on, let your colors burst
Make 'em go "Oh, oh, oh"
You're gonna leave 'em all in awe, awe, awe
You don't have to feel like a waste of space.
You're original, cannot be replaced
If you only knew what the future holds
After a hurricane comes a rainbow
Maybe your reason why all the doors are closed
So you could open one that leads you to the perfect road
Like a lightning bolt, your heart will glow
And when it's time, you'll know
You just gotta ignite, the light, and let it shine
Just own the night like the 4th of July
Rachel with New Directions girls (except Quinn):
'Cause baby you're a firework
Come on, show 'em what you're worth
Make 'em go "Oh, oh, oh"
As you shoot across the sky-y-y
Baby, you're a firework
Come on, let your colors burst
Make 'em go "Oh, Oh, Oh"
You're gonna leave 'em all in awe, awe, awe
Boom, boom, boom
Even brighter than the moon, moon, moon
Rachel:
It's always been inside of you, you, you
And now it's time to let it through-ough-ough
'Cause baby you're a firework
Come on, show 'em what you're worth
Make 'em go "Oh, Oh, Oh"
As you shoot across the sky-y-y
Rachel with New Directions girls (except Quinn):
Baby, you're a firework
Come on, let your colors burst
Make 'em go "Oh, Oh, Oh"
You're gonna leave 'em all in awe, awe, awe
Rachel:
Aweee!!
New Directions girls (except Quinn):
Boom, boom, boom
Even brighter
Rachel with New Directions girls (except Quinn):
Than the moon, moon, moon
Boom, boom, boom
Even brighter than the moon, moon, moon.
