The LOC site does in fact list track names of their online sound files... generally, if you search within an online collection there by artist, subject, collector, etc., up pops a list of tunes from their database.

I was curious whether you had used them in your research. If not, it would be a good place to look around. I use it a lot for spirituals and early gospel (Lomax collections for example). In the Lomax material, there is some info on each item on the page that shows the item and the link to its sound file, but the field notes are located in another area of the collection-- they specify which section of field notes to browse.

Someone has posted here that there is an LOC connection with this piece-- originally I hoped the LOC might have the sound file online, so that you wouldn't need to jump through so many hoops just so people could hear it. Now, tho, I am suggesting you check there to see if any other fiddlers may have been captured playing it, and if so what the field notes might tell you about it.
