I'm in the middle of reading Dave Van Ronk's memoir, The Mayor of MacDougal Street, and I can't forbear to quote his anecdote that fits in this thread. (Timing is everything! I just left off reading the book last night, at this very incident!)

He's been talking about the folk scene some time I think in the late 50s, although he doesn't really date it. I'll pick up in the previous paragraph:

Besides that, he (Bob Gibson) was a good musician, and I sometimes think that he and Paxton were my favorite melodists in the folk songwriter field, Paxton for his incredible simplicity and Gibson for his ability to come up with unusual modulations and chord progressions.
   I also found that I really liked some of those people personally. Gibson, like Cynthia Gooding, was very polished onstage, but offstage they were both wonderfully cynical and funny. I remember years later seeing Bob at Newport with a group of people singing "Kumbaya," and it was turning into one of those really tacky group-gropes, with everybody joining hands and taking turns leading verses--"Someone's crying, Lord, Kumbaya," "Someone's dying, Lord, Kumbaya,"--and it gets arund to Gibson's turn, and he sings, "Someone's kidding, Lord . . ."
