Remembering The Singing 'Mayor Of MacDougal Street'

While the latest Coen brothers movie, Inside Llewyn Davis, isn't a biopic, it is inspired by the life of a real person: the late Dave Van Ronk. He was a folk and blues singer and a central figure in the folk revival of the early 1960s. NPR's Joel Rose has the story of the musician, who was known for his avuncular presence on the Greenwich Village scene.
