You guessed right there, Jack. The original Digital Tradition tune was entered in SongWright, and then automatically converted to a MIDI, and then automatically converted to ABC notation. It you paste it into Concertina.net, it displays the notation with two sharps and rather strange enharmonic spelling.

A Digital Tradition Mirror called Yet Another Digigal Tradition, converts the tunes directly from SongWright to various forms of notation - here (click). The ABC it produces is really, really bad.
I take it that this sort of tune is just too difficult for many notation programs to handle.

I'd like to hear the original singer, so I'd know how close Shar's notation is to the original source.
