I have had a look at the notes from 1975. We recorded throughout the weekend. The men's singing was on both am and pm on the Saturday and I was adjudicating along with Charlie Murray. I had a recording engineer recording the fiddle and other instrumental competitions in the morning and the women's singing on the Saturday afternoon in other halls. I have no info on what was sung in the men's singing - unless I come across the adjudication notes - perhaps unlikely.
