Did a search, this looks like an approximate match. "Fiction" "folk."

There's a story about folk singers in a new Seattle literary review, here. The story's called "What Ha'e the Dobkins Willy?"

I was going to start a thread pointing out the story and then ask if anyone could think of other works centered on folk, but there are several titles here. Never mind.

Since I already went to the trouble of googling up a link--Manly Wade Wellman. His John the Balladeer stories are excellent.
