This elegant tune was written by Billy Mathews and I learned it from his 500 Fiddle Tunes set of CDs (currently 300 tunes are available on his web site www.banjobilly.net). I'm not playing the B part quite right, but I'm working on it. I post my version here with his permission. I actually play it more on the fiddle than banjo, and I've added my fiddle version, which actually matches the B part more correctly.
