I think I mentioned this before, but I don't know if I ever gave you the link.  Now that you're a fancy-pants writer on topics of a folk-music nature, you can find many songs, should you need them, streamed free on Friday, Saturday and Sunday evenings.  My NC NPR station, WUNC, has a program called "Backporch Music" that brings folk, bluegrass, and celtic tunes, among other genres, on those nights from 7 PM (Central) until 11 PM.  Might be totally worthless to you but who knows?
