I've found an image of Liz Knowles' CD, both front and back, and she doesn't give composer's names or say "Trad." on the song titles. She claims a copyright at the bottom of the back, but that could just apply to the arrangements, not the tunes.

So I'm going to assume the song is traditional and public domain. I'm trying to notate it, but it's hard, children, hard.

But, Harry, don't get discouraged. Check back tomorrow and the next day, and perhaps I will have made a MIDI of it. Then, if possible, I can PM you a jpg of the MIDI. Right now i have to go somewhere, but as I say, check back.

But wait - do you happen to have MIDI software?
