Baby, I'm yours (baby, I'm yours)
And I'll be yours (yours) until the stars fall from the sky,
Yours (yours) until the rivers all run dry
In other words, until I die

Baby, I'm yours (baby, I'm yours)
And I'll be yours (yours) until the sun no longer shines,
Yours (yours) until the poets run out of rhyme
In other words, until the end of time
[ Lyrics from: http://www.lyricsfreak.com/a/arctic+monkeys/baby+im+yours_20411993.html ]
I'm gonna stay right here by your side,
Do my best to keep you satisfied
Nothin' in the world can drive me away
'Cause every day, you'll hear me say

Baby, I'm yours (baby, I'm yours)
And I'll be yours (yours) until two and two is three,
Yours (yours) until the mountains crumble to the sea
In other words, until eternity

Baby, I'm yours
'Til the stars fall from the sky
Baby, I'm yours
'Til the rivers all run dry
Baby, I'm yours
'Til the poets run out of rhyme
(fade out)
