As a result of this thread I checked out the photos of YT taken in the late 60s at Bradford Topic Folk Club. If you haven't seen them can I suggest having a look? It gives me a great thrill to see that such a brilliant trio are singing in what looks like a very high ceilinged living room. Brilliant. Inspiring.
Thanx to Heather for the inside info on the Oberlin recording. I wonder if Heather remembers this Bradford gig (Ukrainian Club Clifton Villas)?
