I'm gonna save alot of space and not write the lyrics.  The song has three (okay, 4 - 
if it is only a measure) chords in it and the only time they change sequence is when the 
changes to the chorus and back again.

Verse:
Eb  Ab Bb

Chorus:
Ab  Eb  Ab Gm Bb

Or with Capo on 3...

Verse:
C   F G

Chorus:
F   C   F  Em G

Pretty simple considering the genius behind this song.  There may be a few color notes I 
like a 2nd or 7th, but these chords will keep you in the pocket.
