The vocalist had been MIA for a few days before the gig. With half an hour to go we still hadn't heard from him, so someone went to get him.
When he turned up, he looked, and smelled, like a zombie.
The gig started and the vocalist started to shriek and moan into the mic. No vocals or vocalising, just shrieking and moaning.
The set was (thankfully) cut short when his Mother suddenly appeared on stage, and took him straight out of the venue and to a mental health facility where he was sectioned.
Still not sure how his Mother turned up, she wasn't there to start with. Anyway, it turned out that during the previous few days he had done nothing, except smoke his way through a mahoosive bag of weed, which had led to a psychotic episode.
So during the break we had a disscussion which was reminicant of the conversion in Spinal Tap, to the extent that the guiatrist actually said "well that's a cosy 10 minutes".
