Earlier this week the vocalist argued there was a world of difference between heavy metal and punk, telling the Guardian: "The closest the art establishment ever came to embracing metal was punk. The reason they embraced punk was because it was rubbish.

"The reason they embraced rubbish was because they could control it. They could say: 'Oh yeah, we're punk, so we can sneer at everybody. We can't play our f***ing instruments - but that means we can make out this whole thing is some enormous performance art.'

"Half the kids that were in punk bands were laughing at the art establishment, going, 'What a f***ing bunch of tosspots. Thanks very much - give us the money and we'll f*** off and stick it up our nose and shag birds.'

"What they'd really love to be doing was being in a heavy metal band surrounded by porn stars."
