Consider Bobby Steele, who fronts The Undead, a horror punk band and was the guitarist for the Misfits in their heyday. Bobby got clean and is a Born-Again Christian. He used to be the leader of the worship team at a church in Paramus NJ. He also wears eye makeup live and swears a little on stage.
Vinnie Martell is the guitarist for Vanilla Fudge. He still gigs solo and with the Fudge but is also Born Again and gives talks about his conversion (I've heard him). He can still play a mean guitar, too (I've hear that, too). He seems to lead a fairly normal life.
Mike Keneally got his start as the touring guitarist for Frank Zappa in 1988. Since then, he's released scores of solo albums, tours solo and as part of Joe Satriani's backing band. Mike lives in San Diego with his third wife and daughter, and from what I can surmise leads a pretty sedentary life.
Speaking of Zappa, Frank's son Dweezil lives in a modest home in California with his second wife and kids. While Frank had a wild touring life, Dweezil spends his free time while on tour practicing and he spends his time off tour with his family.
Russell Allen is the lead singer for Symphony X. I saw him when he was with Adrenelin Mob before that fatal accident in Florida that took their bassist and tour manager's lives. He has an autistic son and when off the road, "Sir Russell" (he used to work at Medieval Times) is a family man...on stage he swears like a sailor.
Finally, of course, is Alice Cooper. He's a wild man live but spends his life off stage playing golf.
I suspect there are more "normal" entertainers. But keep in mind, entertainers are, almost by nature, open books. There is a sampling bias insofar as we know more about their lives than we do our co-workers. How do we know that Bob in accounting isn't into wearing a panda outfit after work? How do we know that Mary in accounts payable isn't a cutter? How do we know that Ralph isn't wearing knickers? How do we know that Magenta doesn't snort detergent? If they were in the public eye and the press was rifling through their garbage looking for a story, maybe we'd see that they are freak shows, too.
I am not saying that there aren't a lot of whack jobs in the arts. There are. I'm not saying that Halford's "Mr Hand" story isn't creepy. It is. But I am saying that there may be just as many "degenerates" in the office as there are on the screen or stage.
