Jon attributes his source as Steeleye Span saying, “This was brilliantly and timelessly performed by Maddy Prior and Gay Woods on Hark The Village Wait. It’s worth listening to on headphones for the rather neat stereo trickery.” I can only agree with Jon’s headphone instruction, having just followed it myself. There’s an extensive Mudcat thread on this, with much debate about the tune and also the origin on account of the authorship being claimed by a W.J. Florence, which may or may not be true. You’ll also find lots of detail attached to the Steeleye entry on Mainly Norfolk here, including their acknowledged source. Somewhere down that Mudcat thread is the suggestion that many stage or show songs have made their way into what is now regarded as the folk tradition. I guess if enough people sing them then they make their own way into the later collections, which in the light of the excellent Barry Dransfield song yesterday (and other modern compositions we’ve already had here) is an interesting point. Every song must have a point when it somehow enters the tradition, perhaps for some songs that will have been here, a session in some pub over the last 10 years and so forth. (Kick! …. Run!)
