Jim is a really nice bloke, an important collector of traditional songs, and a very good performer of traditional music.
Regretably someone once told him that he could write songs.
Even more regretably someone once told him it was quite ok for him to do whole sets of his own and other modern stuff.
I also,like Mike O'Leary-Jones, used to walk thirty miles barefoot over glass to hear him. Now I at least tend to keep my shoes on.
