I wrote a melody for this song years ago, but I've never written it down. It's based VERY loosely on a 13th century troubadour melody called "Dehors lonc pre", which can then be used as an instrumentat break. The melody is twice as long as the verses, so each pair of verses ends up sounding like one verse. Or it is possible to leave off the second part of the melody and have shorter verses -- it resolves nicely half way through.
I suppose I could write it down if anyone is interested, but I don't know how to do ABC and am unlikely to have the time to find out. I could probably get my wife to scan it a put it up on the web somewhere, but I don't know how to make a blue clicky thing either.
