Well, the easiest way may be to download the MIDI tune from the online version of the database (right-click on the link and choose to save the MIDI on your computer). Then import it into Noteworthy Composer, and you can do what you want with it. Most of the time, I do what Jon does and use ABCMUS to read the SongWright files, but that's a bit complicated for computer novices.
