Looks like you came across something interesting, Greg. I had trouble with the URL you posted. Is this the one you meant?http://www.ucolick.org/~sla/morris/music/music.html
This leads you to a library of music in ABC format, and has a link to a page about transmitting music on the WWW. This page talks about your ABC files, and should explain how you can play and print them.
It also talks of a converter for Songwright files like the ones on Digital Tradition. I wonder if it will work. I'd sure like to make better use of the tunes on Digital Tradition, but I can't see spending a hundred bucks for Song Wright. I think it's time to switch the Digital Tradition tunes to a format that's more widely available. Dick, are you listening?
