The Inevitable Return of the Great White Dope

This song is essentially a beat loop, but the keyboards
have some weird things going on that can sound like the 
bassline at times, but here's the basic riff:

G------------
D------------
A--3-6-8-4---
E------------

As I said before, when you listen to the song, they either 
have two bass guitars being played, or they have some 
low patterns on the keyboards...
