Do any of these include a sort of throat-clearing noise in the repeating line? I've heard Ed Silverman in SF sing a version with an odd noise in the middle of the "kitty alone, alone a-chm-chm ...[a word or two more, I forget]". Highly entertaining to try to get the sound into the middle of the line, sort of like the African language that includes tongue clicks.
