You’ve had to defend yourself against the accusation of not being punk for almost 20 years now. Do you still consider yourself a punk guitarist?
“My answer is I don’t know if we’re a punk band or not. There’s an argument that we are a punk band, and there’s an argument that we’re not. For me, I’m so close to it that I just think of myself as being in Green Day.
“I’ve got my influences that are anything from British Invasion to early English punk- rock and the East Bay punk scene that I come from. So, that way of playing, the approach to songwriting and the politics come from that, but then there’s the dichotomy of being in one of the biggest bands in the world. People don’t really see that as being punk. It’s like, ‘I like the colour blue,’ ‘Well, that’s not blue, that’s red!’ My best argument for that question is: I don’t know! Billie Joe doesn’t know.”
