Ozzy Osbourne‘s first performance after the tragic airplane accident which killed his young gifted guitarist Randy Rhoads, his tour seamstress, and tour bus driver had the double weight of being a long-scheduled live radio broadcast to America. With Brad Gillis as a last-second fill in, this is Ozzy and band impressively and absolutely live on “I Don’t Know”, no overdubs. It is the lead off song from Double O’s first solo album Blizzard of Ozz. -Redbeard
