This song is a great song, really easy too, the majority of the song is just Am and E. 
only hard bit is trying to fit his lyrics to the guitar and you'll have to figure out 
to put his little runs in too (its too hard to try and explain where they go).

If this tab sucks please tell me, but im pretty sure it's right.

Enjoy xx

 Am AmMaj7 Am7   G    Gm  Bb  Fmaj7  Am

Am
And the mercy seat is waiting
AmMaj7
And I think my head is burning
Am7
And in a way I'm yearning
       G                                   Gm
To be done with all this weighing of the truth.

An eye for an eye
                   Bb
And a tooth for a tooth
                      Fmaj7
And anyway I told the truth
                       Am
And I'm not afraid to die.


 -   The last Am of the chorus also becomes the first Am of either the verse or the next 
its not hard to figure out.
