This was the same year as Knebworth; same line up and similar set. I was pleased cos I’d managed to persuade 23 friends to come, and we were sitting together in 2 rows near the front.
During the interval I caught sight of Beefheart walking behind the curtain at the back of the stage. I jumped up and shouted out. He stopped, turned, looked right at me, smiled, and gave a very slow deliberate wave. This made my night.
The music was absolutely brilliant; similar to Knebworth but tighter, although Beefheart seemed preoccupied and worried about something. Several times during the set he threw the mike down on the stage and walked off, leaving the band to soldier on to the end of the song. Also there was a strange guy with manic eyes who had wandered down to the front of the stage and just stood there, staring intently at Beefheart for the entire set. Half way through Beatle Bones, Beefheart, pointing to a clock which faces the stage, said “that clock bugs me man” and went into a tirade about it before continuing the song.
