Album: The Grand Pecking Order
Tuning: standard

Legend:
h = Harmonic (don't press down on the fret)
^ = Bend note
/ = slide
(#) = note that's possibly there

Alright, I'm pretty sure they use digital delay in the beginning
So I tabbed it as if that is true, 
you should be able to figure it out from that.

INTRO
  h    h
G-9--------------|
D------7---------| 4x
A------------7^--|
E----------------|

Post-Intro
G-----------14--------14--------14--------|
D----/16----14--16----14--15----14--16----|
A----/16--------16--------15--------16----|
E-----------------------------------------|

G-14--------14--------14--------14--------|
D-14--16----14--16----14--15----14--16----|
A-----16--------16--------15--------16----|
E-----------------------------------------|

(Then a rest, and then same notes, just an octave lower)

"He Was Spraying that Agent Orange.."
G-------4---------|
D-7---5---7---5-4-|
A---7-------7--(4)|
E-----------------|

Then, same notes as Post-Intro, but the low F & F#, same pattern

Then near end of guitar solo, play the intro again.

That should be the major part of the song... just listen, you'll get it.
