Angus Young, the co-founder and lead guitarist of AC/DC, has revealed if his late brother, Malcolm Young, got into a fight with the Black Sabbath bassist Geezer Butler, recalling a fun conversation of Malcolm with the legendary frontman, Ozzy Osbourne.

During his latest chat on Talk Is Jericho, AC/DC icon Angus Young has reminisced about the notorious encounter between AC/DC co-founder, Malcolm Young, and the bass guitarist of Black Sabbath, Geezer Butler, in the ‘Technical Ecstasy Tour,’ which began on October 22, 1976, and ended in 1977.

When he was asked about the story behind the incident, Young unveiled the fact that it was not really a fight. He explained that his brother was drinking one night with Butler, and then the bassist suddenly flashed his knife at Malcolm.

Angus said Malcolm took it off since he knew the trick to get a knife away from someone. Thereafter, he asked what is he going to do to Geezer. The next day, Young felt bad about the issue and went to apologize to Butler, according to Angus.

On the way, Malcolm Young bumped into another band member, Ozzy Osbourne. As he said to Osbourne that he’s on the way to say sorry for the knife thing last night, Ozzy prevented him. Angus revealed that Black Sabbath frontman cursed Butler’s famous knife game and advised Malcolm to tell Geezer to fuck off instead.

Here’s what Angus Young said when he was asked if his brother got into a fight with Geezer Butler:

“No, not really. When we were growing up – you grow up like in your local neighborhood and stuff – and you couldn’t… If somebody was looking for trouble, they picked on the wrong guy because he was very fast.

The thing with Geezer Butler, I think they were drinking one night and I think Geezer had some knife or something, and he flashed it at Malcolm. Malcolm took it off – there’s a trick of getting knives away from people, so Malcolm immediately did that and he said, ‘What are you gonna do now?

So it was just the case of that. Malcolm, he woke up the next day, felt bad about it, because we were touring with them, and he thought, ‘I better go and say sorry about the night before.'”

He continued:

“And he went there be bumped into Ozzy Osbourne, and Ozzy was, ‘What are you doing here?’.

And Mal said, ‘I had a bit of a run with Geezer and his knife…’ And Ozzy said, ‘Him and that fucking knife; don’t apologize to him, Mal, tell him to fuck off!'”
