Anthrax Invited Himself Onto Megadeth Album

"One time I was in the elevator with Dave Mustaine and he was working on a record, and I turned round to him and said, 'So when should I show up in the studio to do some vocals? When are we going to do something together, man?," Belladonna tells EspyRock. "He was asking about the new Anthrax album and I was like, 'Hey, I don't know anything yet, no-one has told me about anything yet.' But he says, 'But you're working on it, or something like that, right?'
