Record / CD / Tape
Buzzcocks, John Cooper Clarke

C81 was a CD sold by rough trade in conjuncyion with NME. You collected tokens and sent them to RT for the cassette. NME also printed inserts for the tape. Two Manchester acts were featured Buzzcocks and JCC.

I put this under record/cd because cassette tapes seem to have been erased from history! Oh dear Malcolm whatever happened to "C30, C60, C90 Go!"?
