Mad Person, thanks for asking. I haven't had time yet to write my own tune properly. Last night I sang it to a mish-mash of tunes, based on various other songs with similar structure (Bonny Black Hare being one of them). In other words, I made it up as I went along and I doubt I could do it exactly the same way again.

(Yes, I'd like to record it with our fiddler, who's a Seth Lakeman fan and can do some good impressions of his style. Unfortunately there wasn't time to forewarn her last night, although she was present. The problem is finding the time, and it will be past its sell by date very soon - be good fun though!).
