I just saw Joe Hickerson at a house concert on Sunday, and he sang this song, which I had first heard him sing in 1974. At the house concert, he named his source - from the early 1970s - as Margie Steiner (or is it "Margi?", or "Stiner?") and said that she was a blind woman. He was so happy to have finally learned a song from a blind woman! Or... was he just pulling our legs???

Anyway, he still uses just the Five men, but said others have come up with more constipated men since he first heard the song.
