Probably playing bass in a half arsed cabaret band in an extremely rough pub in North Wales (that narrows it down !)
Singer was rather drunk and very high and was becoming more and more mouthy during the first set. Oblivious to the way his humour was going down, and the massing of ‘the lads’ at the back of the venue, he kept notching it up, and up, and up
Having heard what said lads were going to do to the singer during the intermission, we shipped him off in a taxi, reassembled as our day job (thrash band) and didn’t get a kicking at the end.
Result !
