This article is from the The Osbourne FAQ, by Mike L. with numerous contributions by others.
The following year, in 1988, Ozzy released his 'No Rest for the Wicked'
album. This featured Zakk Wylde (who had his own band 'Pride and Glory') on
guitar, Randy Castillo on drums and Bob Daisley on bass guitar. The album
title again was a bit eerie and the cover showed an Osbourne sitting in a
chair with two girls (looking possessed) and one screaming at him. Zakk,
who had heard Ozzy on Howard Stern mention that he was looking for a new
guitar player, didn't think he had a chance. It was not until later when a
rock photographer mentioned he would be happy to pass along a tape of
Zakk's music, did he then get the audition and the subsequent part.
On August 12 and 13th of 1989, Ozzy played the Moscow Music Peace Festival.
This show featured acts like Bon Jovi, Scorpions and Motley Crue. The other
bands were basically small club bands but of course Ozzy was a world-wide
name and the crowd just went crazy when it was his turn to play.
In March of 1990, Geezer would join Ozzy in releasing a live album titled
"Just Say Ozzy". This would contain some of the No Rest for the Wicked and
Black Sabbath material combined. Nothing to write home about.
