With everything that Crass Records put out in the eighties as far as diversity - Bjork's first band Kukl, the punk-electronica of Hit Parade, the punk-rap of Captain Sensible, you would think that there would be plenty of the ska / reggae influence. It was there but it was rare. Poison Girls did "Old Tart's Song"...
and there was this:
A - Guilty
B - Guilt Dub
