I can't recall the artist's name, but I saw him several times in the central connecticut area, bars, in the late '70s, early '80s. One man guitar (harmonica too?) show. He even had an album out, with a person looking at a giant ball of string. My favorite song of his was a chilling one, set in New England after "the bomb" fell. Group of survivors, not surviving very well. Very dark. I'm trying to find out anything I can: Artist, lyrics, album name, tune.
