Bald Eagle, it wasn't the Free Trade Hall, it was at a club called the MSG (Manchester Sports Guild) behind the cathedral. Jazz downstairs, Folk upstairs. I saw Carthy/Swarbrick there a few times in the late 60's, lots of other gigs, too. Did a couple myself.
They knocked the FTH down, you know. We used to go there from school to watch Barbarolli(sp) conduct the Halle orchestra. Hwyl, Bron.
