All verses start with this riff (repeated twice):

E|----------------------------------------------------------------------
B|-----------------------------3-------------3-2-0----------------------
G|-2-2-------2-2-------------0---0---------0-------2--------------------
D|-0-0-0-2-4-0-0-0-2-4-0---2-------2-----2------------------------------
A|-----------------------3-----------3-0--------------------------------
E|----------------------------------------------------------------------

Then the first verse goes (repeat twice):
E|-0-0-0-0-0-0--0-0-0-0-0-0---3-3-3-2-0-0-0-0---------------------------
B|-2-2-0-2-2-0--2-2-0-2-2-0---0-0-0-0-0-0-3-3---------------------------
G|-2-2-2-2-2-2--2-2-2-2-2-2---0-0-0-0-0-0-0-0---------------------------
D|-2-2-2-2-2-2--2-2-2-2-2-2---2-2-2-2-2-2-2-2---------------------------
A|-0-0-0-0-0-0--0-0-0-0-0-0---2-2-2-2-2-2-2-2---------------------------
E|----------------------------0-0-0-0-0-0-0-0---------------------------
This is like A, Asus, and a variation on E-minor, I think.

The 2nd and 3rd verses start with the main riff, but instead of
going right to the A, Asus, etc. it first goes through these licks:
E|-------0-------------0-------------0-------------0-0-0----------------
B|-----3---3---3-----3---3---3-----3---3---3-----3---3-3----------------
G|---2-------------0-------------2-------------0-----0-0----------------
D|-3---------3---2---------2---3---------3---2-------2-2----------------
A|----------------------------------------------------------------------
E|----------------------------------------------------------------------

Before the 2nd verse goes to the 3rd (and the 3rd to the fade out),
a riff is played with the regular D chord (right after Em stuff):
E|-2-2-3-5--2-2-3-5--3-3-3-2-2-2-2-2-------2-0--------------------------
B|-3-3-3-3--3-3-3-3--3-3-3-3-3-3-3-3-----3------------------------------
G|-2-2-2-2--2-2-2-2--2-2-2-2-2-2-2-2-0-2--------------------------------
D|-0-0-0-0--0-0-0-0--0-0-0-0-0-0-0-0------------------------------------
A|----------------------------------------------------------------------
E|----------------------------------------------------------------------

The fourth verse begins the same way as the other three and fades out
repeating the A / Em stuff.
