townie, just had a look on the net. There is a Nightingale club in Brum in Kent Street. It is an LBGT venue. I found a write-up from Timeout, not sure exactly when it was written, but it does say that Nightingales ( affectionately known as Gales) after several moves in the last four decades that the club is doing well.
Not yet come across any of the previous venues, so possibly could have been sited by the Dolls club at sometime
