I have never heard that, but I agree with him. Anything that a bunch of preppy college kids blare at frat parties is not real punk.
They should get him to replace Simon after season 10. He's English and says/does crazy things.
Crazy does not begin to describe him. Check out his autobiography...interesting to say the least.
Funny thing is, his definition of "punk" is something that is inherently unsustainable. Punk is completely anti-trend. Once "punk" caught on in the 70's, by definition, it should have been abandoned. Lydon ripped his fans who dressed like him because, in order to be punk, you had to do something completely different. Also by his definition, it is impossible to have any true punk band ever again because it has already been done.
That being said, early Green Day (Dookie and Nimrod)has punk roots based on The Sex Pistols, The Ramones, etc. American Idiot had punk influences but was far more of an alternative rock record.
