This is a very easy and simplistic song to play. It really is the same riff
over and over again until you feel like stoppin'. That is, it consists of TWO
riffs, but two one bass plays each. Alright, the first bass begins as follows:

G--------------------------------------------------------
D--------------------------------------------------------
A--------------------------------------------------------
E---2--2--2/-9--9\33--3/10-9-10--------------------------


And after playing that a few times bass #2 joins:

G--------------------------------------------------------
D--------------------------------------------------------
A-------------0------0-3---3-3-0-------------------------
E---2-0-2---22-2---2-------------2-0---------------------

Nothing more to it other than play until you drop
(or, as mentioned above (and I quote:), "feel like stoppin'").
