1962 --- Roscoe was singing in an out of the way grotto on the 3rd floor of Ida Noyes Hall at the University of Chicago Folk Festival for just one other person and myself. I had asked him to do "The Unreconstructed Rebel" and he didn't want to sing it for the whole audience at a concert so we went off after a workshop and he sang it for us. Then he took my guitar, tuned it to an open chord (G probably), took a knife out of his pocket and played 2 or 3 songs sliding the knife blade on the strings. It was one of those transcendant moments that I'll always remember.
