Not the best tab in the world, but you should be able to get the idea of how to play 
one.  It's a lot of fun with a group.

e|------------------------------------------------------|
a|------------------------------------------------------|
d|------------------------------------------------------|
g|-0h2-2-5p2-2-0h2-2-5b-2----0h2-2-5p2-2-0h2-2----------|
b|-0--------------------------0------------------0------|
e|-------------------------------------------------3----|

Okay, that is the main riff, and it pretty much just repeats through the song, but there 
a few places where he adds an ending like this:

e|-----------------------------------------------------3----3-----|
a|-----------------------------------------------------3----3-----|
d|-----------------------------------------------------0----0-----|
g|-0h2-2-5p2-2-0h2-2-5b-2----0h2-2-5p2-2-0h2-2-------0----0-------|
b|-0--------------------------0------------------0-----2----0-----|
e|-------------------------------------------------3---3----2-----|

and then he just goes back into repeating the main riff.
