Mrr, I'll see if I can find time to write out the tune and post it on Alan's page later today. (then you'll be able to click on it and play). Alternatively I can send you MIDI file of it, as an email attachment. It has its own tune and I can't think of anything else it sounds like. Ruth Pelham has CDs out, and I think other people have recorded this, but I learned it in the folk community. Dunno who's recorded it.
Blessings,
Barbara
