As posted on the forums by a band member, straight from the horses mouth.

Intro

Em G C 
Bm G Em
Em G C
Eb

Then the riff that keeps hitting is...
C,B,G,Eb

Then there is the verse which is more of a riff but the chords are..

Em Am Bm C,B,G,Eb 
Em C Bm C,B,G,Eb
Em C,B,G,Bb

Pre-Chorus (Gee whizz...)
Am Then on the last beat of the bar hit Bb
Am Again, swing onto a Bb
C,C,C,C,C,C,C,C, C,B,G,Eb

Chorus
Em Am Bm C,B,G,Eb
Em Am Bm C,B,G,Eb

And then the only other bit is the middle 8 (after the brass bits) which goes...
C D Am C,B,G,Eb

Then in the final chorus it has the extra wo-oh-oh...

Last Chorus
Em Am Bm C,B,G,Eb
Em Am Bm C,B,G,Eb C C,B,G,Eb Bm C,B,G,Eb

That's pretty much it. The riff in the verse should easily be learnable if you 
mess around on those chords.
