Hi, Ian - I added the line breaks on your ABC tune to make it look right. It plays perfectly on my ABCMUS, so it seems to me that you've mastered ABC quite admirably (something I haven't done yet). I'm duly impressed. Guess I'd better learn ABC myself, eh?
Did you use some sort of ABC program to enter the tune, or did you just type it in on a word processor?
