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.

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.

For instance, our music, They Might Be Giants, has this element of humor, which is probably the most uptight part of what we include in our music, because we're in part very self-conscious guys, and we want our music to stand up to the test of time, not just be visceral comedy records. We love humor and comedy, but there's this aspect to it that runs counter to what is included in most music.

Being in a band, a lot of times people think of what you're doing in terms of a competition. They talk about where you are professionally in your career, and all this other stuff. And if you're a lifer, you know it's going to be ups and downs. It's not like anybody is always just steady on.

In Germany there's something about rock music much more political than it really is - like everything you were doing was an indictment of the American culture. I read an interview with one of the members of Sebadoh. He was saying he had just got back from touring Germany for the first time in five years or whatever, and one of the interviewers asked him, "Why aren't you still relevant?"

There's so many simple things that can be done to change our carbon footprint, and to reduce our carbon footprint.

If you're looking at the array of performers, there's just a lot of people that it's about getting closer to them. That's not really our focus. It's funny, with the kids' stuff, we really sell ourselves as the MC, but it's much more like we're Ed Sullivan than we're like Sting. We're just the presenters. And that's an idea that we're very comfortable with.
