GTR 1 Riff

E-3-------------------

The riff for guitar 1 goes through the vast majority of the song.
The second guitar kicks in with the verse and plays the chords that match the root note of the main riff.

G
  I'm Me
C
  May be
D
  God damn
C
  I am
G
  I can
C
  Sit and
D
  Sing and
C
  Know me

Those lyrics are from memory and could be wrong. But you get the gist.

the chorus goes like so:

G      C          D       C
If you want to destroy my Sweater
G         C               D     C
Hold this thread and then walk away
G          C
Watch me unravel
     D         C
I'll soon be naked
             G                  C           D      C
Lyin' on the floor, Lyin on the floor, I've come Undone.
