Just discovered your question. I was brought up in West London, my father being Secretary of the West Ealing PSA Society. This was founded in 1913 under the wing of the West Ealing Methodist Church (demolished soon after the WW2), but built its own meeting hall where Sunday afternoon meetings were held. These would last about an hour and a quarter, with 4 hymns, an address by a visiting speaker, a soloist, and the PSA Orchestra. The members were from all Christian denominations and none. During the week billiards/snooker, indoor bowls, table-tennis and whist drives took place. Now and then "Socials" would take place, with party games, dancing and a visiting entertainment. The PSA managed to maintain its membership until about the 1960s, when a steady decline led to its end in the 1980s. The hall is now home to a day nursery.
