"Blue Moon" did go out on it's own, Jim. To Maine Road initially. Then it came back as an evolved song to our club. Then it evolved some more!

Out of interest, if a song cannot evolve within the confines of the folk club community, how can some of Ewan MacColls songs have evolved into folk songs? Other than "The first time" and "Dirty old town" which other of his songs have 'made their own way in the world'?
