Back in 1954 I visited a Congregational church-hall in Benchill a few times, to help an office pal who was a church member.
We painted backdrops for a couple of shows they were putting on; one was a play which required a wood-panelled wall behind the action on stage. The other was for a minstrel show (before such things were frowned upon) - the troupe called themselves "The Congo Minstrels". I can remember "Mr Interlocutor" sitting front centre in his top hat, a lot of corny badinage between him and "Mr Beezlebub Bones" - and lots of tambourines being rattled. All pretty harmless stuff, but in all this excitement I cannot remember the actual building at all. Maybe it was a wooden hut.
Sorry, this won't help much, but your query brought back some memories.
