The controversial move was a result of legal action between the departed duo and Ozzy's management. Now Bordin tells Radio.com: "That was a really kind of f***ed-up thing. It's funny that no one's actually mentioned that.

"That wasn't what I was going in expecting to do. It wasn't the way it was presented to me at all. I never knew that - but that doesn't lessen the fact that it happened."

He refuses to "throw anyone under a bus" by suggesting who might be to blame, but adds: "I will say this - to hear the original guitar, bass and drum tracks in my headphones while I was recording was one of the most insane things I'll ever experience.
