The crux is that in 2002, bassist Daisley and drummer Kerslake were removed from the Blizzard Of Ozz and Diary Of A Madman albums, after they took legal action for unpaid royalties. Their parts were replaced by Robert Trujillo and Mike Bordin who were in Ozzy's band at the time.
Ozzy told Pulse Radio: “Believe me, it wasn’t my doing. I mean, I didn’t know that was being done, ’cause Sharon (Osbourne) was fighting all the legal things that were going down at the time. I said, ‘What did you do that for?’ And she said, ‘The only way I could stop everything was if it went to that level.’ And I said, ‘You know what, whatever the circumstances were, I want the original thing back.’ I mean, I wouldn’t have done that.”
Well, mistakes are mistakes and I am glad it's being fixed. Now I can actually get those albums on CD soon.
