“I Don't Know” by Ozzy Osbourne

"I Don't Know" comes off Blizzard of Ozz, the 1980 debut Ozzy Osbourne made on his own after Black Sabbath fired him in 1979. There was no outside hired gun behind the desk: Osbourne, guitarist Randy Rhoads, bassist Bob Daisley and drummer Lee Kerslake produced it as a band, with Max Norman engineering, and the songwriting credit goes three ways, to Osbourne, Rhoads and Daisley.

That makes it a document of a brand-new outfit with something to prove: Ozzy's voice out front, Daisley stacking backing vocals behind him, and Rhoads on the first of just two studio albums he would cut with Osbourne before his death in 1982.
