Thanks to Ian for making this available.
As a folk club organiser of the period it was made, I thought it very representative.
As for traditional performers, if some people posting messages here had listened more carefully, the introduction made it clear that it was intended to be representative of folk clubs at the time. In the few years before 1982 (thanks to film maker Barrie Gavin and Bert Lloyd) and in the years since (thanks to the BBC with films on the Coppers, and a few others) traditional singers and musicians have been seen on TV. I only remember this Finger programme and The Other Music documentary representing the folk club experience. There was some folk club film footage in Folk Britannia, though curiously they didn't use any Finger footage.
