From Zappa Wiki Jawaka
Ozzy Osbourne (December 3, 1948) is a British rock singer and frontman of the band Black Sabbath. Later he went solo. During the 2000s he became famous for a whole new audience as the star in his own reality TV series, "The Osbournes".
Osbourne recorded a version of the Bee Gees Stayin' Alive with Dweezil Zappa which was not released due to record company disapproval. Donny Osmond re-recorded the vocal for the track which appeared on the Confessions album. The Ozzy version was eventually issued on the Prince Of Darkness 4CD set.
