Just in case it isn't clear, I never thought folk music died. It just went back to the front porch, living rooms and dance halls where it's been since Kendall invented the front porch. When I listen to the stuff that was popular in the 60's, for the most it doesn't hold up well for me. But, Clarence Ashley, Leadbelly, the Carter Family and the rest sound as fresh to me now as they did the first time that I heard them.
A lot of good comments in this thread.
