Book excerpt: Heavy metal legend Ozzy Osbourne shares his unbelievable story for the first time in this tell-all memoir of sex, drugs, and rock-and-roll. Take what you thought was "rock and roll excess" and double it–you still wouldn't be anywhere near the dizzying life of Ozzy Osbourne. Born into a life so poor that the whole family slept in one room, music was his salvation, and his band Black Sabbath went on to change the musical landscape forever. But along with the rock and roll came the inevitable sex and drugs, and Ozzy soon fell into an epic relationship with booze and chemicals. The stories of Ozzy's days on the road are now those of legend–biting the head off a live bat, the tragic plane crash that took the life of his best friend and writing partner Randy Rhoades–but few know of the real heartbreak he suffered during those days of hard living. In the end, it was the love of his family that saved him. Told for the first time in the rocker’s hilarious and inimitable voice, Ozzy finally comes clean.
