Reality TV star Jack Osbourne is to interview his wildman father Ozzy Osbourne for a new TV show about how heavy drug users cope after years of abuse. The 21-year-old, who has had his own well-publicised battle with drugs and alcohol, will question his Black Sabbath frontman dad on the darkest days of his addictions. Jack also plans to speak to other veteran rockers including hedonistic Rolling Stones survivor KEITH RICHARDS.
