Unless I've missed it, I didn't see it on here, but I'd reckon that this song divides (albeit simplistically) into two threads - the "Tide flows in, tide flows out" version and what it's convenient to call "the Kidson version."
I'd venture that most revival singers of a certain age who performed this song got their version from one of two sources (a) ("tide flows in etc) from Shirley Collins or (b) the late Tony Rose, for whom JATTWF was almost a signature tune.
I on't think 10,000 Maniacs mangled version was ever a factor.
