Guitarworld.com have posted a cool retro feature in their GW Archive called What's Your Most Spinal Tap Moment? "Ozzy Osbourne, Billy Gibbons, Angus Young and more share their most insane rock-and-roll stories ever!" A coupla excerpts follow:

AC/DC's Angus Young:
"Many years ago, when Bon [Scott] was our singer, our manager had “a brilliant idea” to hire actors who would impersonate police officers and “arrest” us onstage. Unfortunately, this was carried out at a gig in Sydney [Australia], in front of hardcore AC/DC fans that started rioting as soon as “the police” came onstage. Minutes later, the real police force came in to control the riots. Unfortunately, we couldn’t distinguish the real cops from the fake ones. Bon thought he was hitting the fake cops, but he was messing with the real ones. One of the cops gave orders to his “colleagues,” who were, in reality, the actors! I just stood there laughing my head off, which the real cops didn’t appreciate. In short: total chaos ensued.

OZZY OSBOURNE:
"After watching the “Stonehenge” scene in Spinal Tap, with the midgets, and seeing ALICE COOPER incorporate a hanging act into his show, I thought, Why not fake the execution of a midget onstage? The one midget actor who could free himself for an eight-month tour turned out to be an alcoholic. He showed up late; he was drunk… It got to me after a while. So one night when he wanted to get on the tour bus, I threw him into the luggage compartment. Somebody grabbed me and said, “What you’re doing is not only illegal but inhumane!” I lost it. I yelled: “He’s my fuckin’ midget and I’ll fuckin’ do what I want with him!” There was a silence, and then a small voice emerged from the luggage compartment: 'He’s right: I’m his midget and he can do what he wants with me.'

BLACK SABBATH guitarist Tony Iommi was a consummate practical joker, though not a very subtle one. One time, he shat in the dip sauce at some record company event. It was interesting standing there and watching the executives indulge.

In my wild years, my wife Sharon used to accompany me on tour to prevent me from committing adultery. Some nights, she waited up for me in our hotel room. One time, I was so drunk I’d forgotten all about her presence, and when a lovely Japanese girl chatted me up, I thought: Fuck me! Sex with a gorgeous Eastern girl is one of my big fantasies, so I’m not letting this one go! When we got into the hotel room, Sharon wasted no time: she decked the Japanese girl with one right hook. In the morning, I woke up alone in the bed, a bunch of Alcoholics Anonymous brochures beside me."
