And he needed to use the facilities. The vocalist was in the middle of the first song when he made a beeline for the john. Luckily, the bathroom was next to the drummer. With the bathroom light on and the door wide open, patrons looked on as Dave bowed over the bowl. Not that this interrupted the tunes. The band played on while one of the musicians announced, "Dave's really sick. He's got a 107." Within seconds, the Porcelain God was back on stage. His "666" T-shirt was still clean. To clear his throat, he took a swig of beer.

That set the pattern: Drinking, puking and singing—practically simultaneously. And jumping like a pogo stick to the music. And springing at the crowd like a jack-in-the-box. And holding up a two-foot-high cross with Jesus on it.

Before Dave put the cross away, he told the crowd: "It's the second coming."
