They absolutely ruled when they played with the Dead Kennedys and Test Tube Babies all those years at the Poly - ferocious, furious and tight as fu*k. I went to see them a year or two later at The Richmond with Crucifix, but they weren't allowed through Dutch customs at Schiphol earlier in the day.
Finally got to see them again 7 or 8 years ago in Croydon playing to about 15 punters. Didn't stop from being utterly effing spellbinding though.
Haven't seen them since a London gig mid 80s - supporting DK so maybe the same tour? Don't recall PTTB tho. Good the hear they could still deliver years later. Post a review if you go on 7th - I'd interested to hear about the band and audience.
