This from Dave Van Ronk's book:

"One interesting thing is how few of the people who had been around in the 1950s were involved in this scene. Most of the acts who became popular in the 1960s came from elsewhere, to the point that by about 1962 two-thirds of my close associates were people who had blown into town in the last year or so. I did not particularly notice this at the time, but when I go over the names, there is a striking discontinuity between my coworkers in the Folksingers Guild and the people who became the mainstays of the Village scene once it picked up steam."

Van Ronk hung on. Will Llewyn Davis?
