Black Sabbath icon Ozzy Osbourne was "whacked in the gut" by his jealousy of the band's replacement after the singer was kicked out of the group in 1979

Ozzy Osbourne ’s loved ones have been joined by the Black Sabbath legend’s celebrity friends, and fellow musicians, as they prepare to lay him to rest today. The rocker died aged 76 on July 22, after a long battle with Parkinson’s and other health problems – although no official cause of death has been announced.

"I didn’t realize then that I would never see Ozzy again after that night," Butler writes of the July 5 "Back to the Beginning" show in England.
