You're like, "I don't want to argue with Dr. Drew on national radio." You're like the invited guest. But at the same time, as a thinking person, it's very difficult just to stand by and go, "Yeah, man, it's cool."

A lot of times I'll post things on Facebook, and the immediate response will be like, "Stick to the music!"

I feel like the future is unwritten. So many of the things that we write now haven't been about educating people on the environment, they've been about disseminating facts. But I feel like it could be productive to write something that explored directly the idea of fragility.

Sometimes you have to wonder if there isn't an ejector seat built into having a popular-music career. We were lucky when we started. We were already old when we started - you could have described our first album as "aging Brooklyn guys." We were in our late 20s. We weren't octogenarians, but a lot of bands were already younger than us. Fortunately, we've held on to our manly good looks.

That's what I call 'Guiliani Time', my friends. 'We've got a problem. Let's kill it.'

So we've done science songs. We've done historical songs. A lot of people would like us to do more historical songs. Our history record would probably be like the people's history of the United States, set to music.

Worlds going to hell anyway, have a good time.
