In Ozzy Osbourne's memoir announcement shortly before his death, the Black Sabbath rocker said he's not ready to go anywhere.

Ozzy Osbourne, the Prince of Darkness and heavy metal icon, has died at 76. The cause of his death is unclear at this time. This comes after his legendary final concert on July 5, which sold out at Villa Park, drawing a crowd of over 42,000 strong. The final performance raised over 190 million for children's charities.
