Very interesting thread. I think I'll reserve judgment until I've seen the movie.

Thanks for the links Mark (Terri Thal, and the Ballads, Blues and Bluegrass DVD). My daughter kindly got me the "Mayor of MacDougal Street" when it came out and I loved it. I'm too young - just - to have made it over to Greenwich Village in 1961 but I wish I could have. I've ordered the DVD so let's hope it plays in the UK. Worth a punt anyway.
