Here's the chords!  I figured them out by ear, and I am positive that they are 100 
correct.  The other versions of this song didn't sound right to me, so I figured out what was 
with them.  I think this is how Nick plays it, too.

Capo 2 fret

Intro G (320003@1)name="chord_320003@1">G C (x32010@1)G (320003@1)name="chord_320003@1">G D (xx0232@1) 2x

verses: G G C  G G  D

Chorus:
C G D Em

C G D Em

C G D Em

Am G C C G

That's it!  For the rap part just play the intro again!  Simple as that!  Please rate!  :)
