Yes, the Singers Club at the Princess Louise certainly started in the 50s — first off there was a skiffle club there where Henry Morris was leading resident; then the Nancy Whiskey Club started in 1956; then the MacColl-Seeger Singers Club took over in, about, early 57. I was a regular there 57-58 but don't remember Joe Heaney appearing. If there was a pub-club in Kilburn at same time, I should expect it to have chosen a different name to avoid duplication or confusion. I think the other pub refd above by Ralphie where the Singers later appeared was The Bull & Mouth.
