Can thoroughly endorse that too. It was in Edinburgh for several weeks earlier this year, with Bob Fox doing the singing. Has to be one of the best theatrical productions I have ever seen. My only reservation re the music was that we never got enough of each song, but not being just a "folk" audience, I guess a lot of people there would not know the songs as well as I did!
I read somewhere that they were phasing out live musicians and using recordings which would be a shame if true.
