Hedy West (1938-2005) wrote perhaps the best loved folk song in recent American history, ‘Five Hundred Miles’, which she put together from fragments of a melody her uncle had sung to her in her Georgia childhood. Although she was a gifted songwriter she was also well known for her recordings of traditional songs, and for her ‘clawhammer’ banjo style. Here she is playing the traditional song ‘The Wife of Usher’s Well’.
The Mainly Norfolk site seems oblivious to the fact that Hedy West recorded this song, although it does give a good summary of the various British recordings. There are several interesting discussion threads on Mudcat Café concerning the history/meaning of this song; this one would seem to be a good place to start, and there are links to the others near the top of the page.
