Social issues are a big part of your music. Has that also evolved over the years?
It's pretty much the same. My very first album had love songs, had folk songs, had country songs, and also had Universal Soldier and a couple of other social issues songs. I write about things I'm passionate about, but it might be very ordinary things. Things we see every day, like trees in the countryside, or it might be about political things.
I was lucky enough to come up in the folk music era. In the '60s, it a lot like now. For a long time it was silent. The playlist was very small. There was a lot of payola. But in the '60s everything opened up, so everyone was listening to each others' music. Now, I think after a real long and repressive time in music, we have the Internet and people can find each other again. People can find music from all over the world, and I think it's great. I feel very at home.
