I couldn't find any good tabs on line so I figured it out. All the chords are 
right except for maybe the F#m and the second to last A. But they sound fine and 
work, they just may not be exactly what he plays. I used a live video of him 
playing to figure this out so it may not be exactly like the studio recording.

The song is in E major if that helps.
