From a Revolver interview, referring to auditioning a guitarist for Ozzfest aught five:
Revolver: Have you held any auditions?
Ozzy Osbourne: "I tried out that Buckethead guy. I met with him and asked him to work with me but only if he got rid of the fucking bucket. So I came back a bit later and he's wearing this green fucking Martian's-hat thing. I said, 'Look, just be yourself!' He told me his name was Brian, so I said that's what I'd call him. He says, 'No one calls me Brian except my mother.' So I said, 'Pretend I'm your mum then!' I haven't even got out of the room and I'm already playing fucking mind games with the guy. What happens if one day he's gone and there's a note saying, 'I've been beamed up?' [Laughs] Don't get me wrong, he's a great player. He plays like a motherfucker!"
Upon reading this, I lost all my respect for Ozzy and gained so much for Buckethead.
