Ah, to be young.... A guy I know jumped off the balcony at a PiL show at the Palladium in Hollywood. Everyone cleared out and he slammed into the floor. After about a minute he pulled himself up and walked back to the bar. Next morning he asked "What the hell happened to my head and ribs?"
A friend caught the last U.S. Pistols show at the Cow Palace, said it was disgusting with Rotten spitting and (etc etc) on the audience. I later saw PiL several times in Boston, he'd calmed down a great deal.
The Pistols did have good taste staying at the (then-Westin) Hotel Miyako in San Francisco (where Sid V. broke the lobby window in a temper tantrum). For years I stayed there on business, always getting a corner room on a high floor. Two corner walls of solid glass with sliding Japanese rice-paper shutters. IMO the best hotel in SF at a very reasonable price.
The Chelsea however leaves a great deal to be desired.
