This is a really fun riff to play, and pretty easy once you get the hang of it.
I'm actually surprised this hasn't been done yet :-/ Oh well.  Here's my 
interpretation of it...don't tear me apart, 'cause this is my first tab :D

Tuning: (BEADG, but it can be played BADG or BEAD for us four-stringers)

There is really only one riff to this song, and than he just improv's the heck out 
of it, using a LOT of slides.

Main Riff:
G:| ---------------------------------
D:| ---------------------------------
A:| -------2---2h3----------2---2h3--
E:| ---------------------------------
B:| -x-x-0---0-----0--0---0---0------

NOTE: I can't tell if he slaps and pops in this...I don't think he does, but I could
be wrong.  Experiment with it, I guess.  Enjoy!  Comments appreciated!
