In 40 years of ghoulish theatricality, Alice Cooper concerts have featured mock executions and live chicken dismemberment. Now two fans are battling in court over their own contribution to the mayhem.

One man is charged with assault after a fight at a Cooper concert in England last July. The defendant, a disabled man, is accused of infringing upon the personal space of the man next to him in the front row of the balcony -- by removing his prosthetic leg.

Andrew Miller says he put his stump on the ledge to relieve his pain, whereupon the alleged victim, John Lynch, began elbowing him. Punches were thrown, with Miller apparently getting the best of his opponent -- he broke his hand landing one blow. "I was trying to save my life," he told a jury. "I was trying to stop myself from getting punched over a balcony."

Which, for Cooper's fans, would have looked like part of the show.
