Actually, it's a tune INFORMATION request.

Does anyone know the origins and proper key of the tune "Fort Belvoir Schottische"? I learned it in D in dulcimer, but then I learned pretty much everything in D on dulcimer so I don't know if that's the proper key or not.

It doesn't seem to be a very common tune. Googling it was remarkably unproductive even with variant spellings. It's on Scott Odena's dulcimer recording, Song for Grandpa, but there are no sound clips that I can find.
