I can add a little to this since I appear in the clip!! I am the one in the pale brown sweater with his back to the audience. My wife Helen is sat next to me and opposite us facing the canera are Graham and Eunice Mathers. When Folk Union One was formed Eunice was membership no. one.

When Norma came back from Montserrat the Watersons re-formed and John was down in London so Bernie Vickers - the tall bearded guy - joined the group. Their first concert back had Planxty as support. Bernie left shortly afterwards and Martin took his place.

The clip shown, and I seem to remember there are others from the same play - was filmed upstairs in the Haworth Arms Beverley Rd Hull. It was (and looking at the website still is) a student oriented pub near the University.

The TV company made the fatal mistake of supplying real beer and we all had a big singing session afterwards which led to someone falling off the stage whilst singing General Taylor.
