Hi, Steve - the link I gave is to Folk Music - An Index to Recorded Resources, a service of the Milton S. Eisenhower Library in Baltimore - it's part of Johns Hopkins University, and it also has the excellent Lester S. Levy Collection of Sheet Music. For more online resources, check our links page here at Mudcat.
But if Rounder can't help you, I don't know where to find a recording. I've never heard of the group before. Maybe some nice person will have the record and offer so send you a tape or e-mail you a recording. Refresh this thread once a day for a few days (by posting a new message, with just the word "refresh" in the body), and see what happens.
