I am really surprised that nowhere in this discussion is Bill Monroe's "Ashland Breakdown" mentioned. Monroe recorded it on March 10, 1975, in Mount Juliet, Tennessee. I have it on his American Traveler (County, 2000), a collection of instrumentals. The notes credit Monroe as composer, though that's hardly the definitive word. He claims authorship for at least one other piece I am reasonably confident he didn't write ("Goin' Up Caney," which I believe he learned from his Uncle Pen).
In any event, it's the melody Si Kahn used, consciously or unconsciously, for his later "Wild Rose of the Mountain." The Steep Canyon Rangers, who sometimes accompany Steve Martin on record and tour, used the tune for the title song of their 2007 Rebel album Lovin' Pretty Women.
