There is more similarity in our subjects, and even more in what we don't take for our subjects. We're folksingers, he long before me. And there are not a lot of modern folksingers, at least by my definition. Folk music is the music that rises naturally from a community. Making music is an absolutely natural thing to do, as natural as running, as natural as speaking.
People just sing.
And left to our own devices, we'd sing about anything we'd talk about. People have always sung their protests, just as they have sung their love. They made up songs about their friends. About tragedies, controversies, work. They made up songs for weddings, played tunes for the dance, made up a ditty and dedicated it to someone for a birthday.
