That was probably the craziest show I ever saw, and that includes an evening that involved Sonny Rollins and King Crimson at different venues. One of the bands that led off before DK was a band that was all really tough looking punked out women in fatigues backing a skinny guy who must have been pretty close to seven feet tall. They would crank up and thrash away while he would yell "aggravation" into the microphone multiple times and then fall over. They would stop, he would stand up, and say "hey, man, can you turn down the lights, man. It's hurting my eyes, man." And then take off a piece of clothing. The band would crank up again, and the whole routine repeated. They were done when he was down to nothing but a pair of sheer pink panty hose and nothing else. To call it nuts was an understatement, and it wasn't much more nuts than any other part of that show. Of course the Kennedys blew out the walls. Jello Biafra must have had a really long cord for his mic, because he would flop into the audience and get passed around on top before the audience passed him back to the stage. The speaker stacks looked like they were about two stories tall, and there were crazed punks who climbed them. I don't think anybody made it to the top before falling off into the audience, but I don't remember now. I do remember thinking, even as an irresponsible young person, that it was a dumb idea. The security guys chased stage divers all over the place and threw them off the stage, which was the whole point. They also were yanking people off the speaker towers on a regular basis. It all became part of the show. As far as I know, there were no injuries beyond some pretty good cuts and bruises. I saw a few black eyes that were on their way to swelling shut. I had a few of those over the years, and they are hardly worth writing home about.
There's joy in weirdness and exuberance. I would go to a show like that and dive right in, even now. Dweezil is a different kind of wildness, and I would enjoy that very much, too. Zappa style virtuosity in the service of musical experiments is just a different kind of exuberance.
