Kind of along the same line; mid 70's Pink Floyd in Los Angeles at I believe was the Sports Arena. I had bought 6 tickets and sold two of then to the catering truck driver. Ed Davis was the police chief at the time. He wasn't about to let any dope smoking hippies in his jurisdiction. The cops were searching cars at random, frisking everyone and down right spooky. So to compensate we chain toked rag weed all the way down there. Didn't see the catering truck driver & his gal till we sat down. They compensated by dropping acid. I don't think they blinked for 2-1/2 hours. Good show as it was right after Dark Side of the Moon. What a bunch of crazies we were. But no regrets.
