Ozzy Osbourne once soaked a room in shark's blood while on tour with Black Sabbath.
The singer's former bandmate Toni Iommi admits at the height of the band's hellraising days Ozzy decided to go crazy with a dead shark because the group weren't excited by drugs anymore.
Toni said: "With drugs you always get bored, so you must do something to one another. Like Ozzy hauling a shark through a window, dismembering it and soaking our room in blood."
The 63-year-old guitarist - who has just released his memoirs Iron Man: My Journey Through Heaven and Hell With Black Sabbath which details his life with the band - accepts his own drug use caused problems in his life, but he insists he was able to get sober without going to rehab.
He added to the New York Post newspaper: "We had management problems, I married four times. Was a lousy husband. I suddenly didn't feel good, so I stopped drugs. No rehab. I'm a country squire I live on a farm with dogs and chickens. All I want is to work. I'm dedicated to working.
