Bodysnatchers too experienced(v1) bass tabs

Song: Too Experienced
Artist: The Bodysnatchers
tabbed by: Iisaw Kookostawis (joannie@sprocket.viathe.net)
transcribed from The 2 Tone Collection, as far 
as i know the origonal singles aren't any different. 

riff 1 is what is played throughout most of the song (chorus and verses)
in some places without singing there is only riff 1a. Listen to recording
to verify what goes where.

riff 1a

G:--------------------2-----|--------------------7--------

G:--------------------------|-----------------------------
D:--------------------------|-----------------------------
A:--------5--7--------------|--------2--2--5--5--2--0-----

after the second chorus, replacement for riff 1a:
