MDC - "John Wayne Was A Nazi" Tablature

Bass tab for "John Wayne was a Nazi" by MDC
from "Millions of Dead Cops"

intro
G---------------
D-7-7__75-------
A--------7575---
E------------75-

riff 1
G-----------------------
D---7----5----3-----35_-
A-----------------------
E-55--533--311--133-----

riff 2
G------------------
D------------------
A------------------
E-5555333311113333-

after the intro riff 1 is played 16 times and
then riff 2 is played until near the and of the
song when there's a rest for one bar and then
riff 2 again 4 more times, listen to the record,
it's not difficult. Having said that riff 1 IS
difficult,
I can't play it without some of the strings
ringing,
mainly the E and A strings. I can damp down A by
putting
my little finger on it but E still rings. Any
suggestions?
I'm not sure about the intro, he plays it too
fast for
me to hear, but that sounds about right. (-5___-)
means sustain 5.
Thanks, Nick
