Pretty easy tune, though this won't work with the studio version. 

It's based off of the version they played at Coachella
(http://www.youtube.com/watch?v=lXXr3ODPvm4&feature=related). 

Pretty sure he uses a capo on the first fret, but this is without it.


Eb                     Dm
All I want in lifes a little bit of love
   C                 Bb
To take the pain away
        Ab          Gm
Getting strong today
  Ab                 Bb
A giant step each day

That pretty much repeats itself throughout the song.
