Coldplay

Ohhhhh...
[Chris Martin:]
Once upon a time somebody ran
Somebody ran away saying fast as I can
I've got to go... got to go
Once upon a time we fell apart
You're holding in your hands the two Halves of my heart
Ohhhhh, ohhhhh!
Ohhhhh...
[Rihanna:]
Once upon a time, we burn bright
Now all we ever seem to do is fight
On and on...
And on and on and on...
Once upon a time on the same side.
Once upon a time on the same side, the same game
And why'd you have to go have to go and throw it all on my fame
[Chorus:]
I could've been a Princess, You'd be a King
Could've had a castle, and worn a ring
