God bless John Robert "Ozzy" Osbourne and his family. I think he was okay with Black Sabbath but I liked him better on his own. And Sharon was a blessing to him. Ozzy can sing and perform but cannot get two pennies together. But Sharon can and it is because of her that they had a nice pot to piss in.
One of my favorite stories is from Zakk Wylde when he was struggling with his drinking. "When Ozzy tells you that you have a problem..."
As for biting the head of a bird, that was an accident. But it freaked everyone out and that made for good press.
Biting the head off the bat was also an accident. They were performing outside and the temperature was in the 40s F. At that temperature, bats are sleeping. Someone threw a live bat on stage and he thought it was made of licorice. As he bit into and realized this really was a bat, he was rushed to a hospital to start injections for rabies.
I think one of his greatest sorrows that never really went away was losing Randy Rhodes.
He may have been the Prince of Darkness but he was had crucifixes around the house hung in the proper fashion.
Speaking of Keith Richards, he may not even have started pre-need funeral arrangements.
