Further to the Church mentioned by Lady Penelope.
The Church took place every sunday in Bagley's club at Kings Cross - I live on a narrowboat there and it was murder! Every Sunday we had a self imposed curfew from 11am until 1pm and 4pm until c6pm. I know the majority of the users were just being friendly - I found out my nephew had been a visitor when he was in the army; but there was a nasty minority who used to urinate in the gate of the mooring, throw things from the bridge above the canal - once it was a two litre bottle of water, another time I found a half bottle of gin (I think). They shouted abuse and really rude remarks, I also once saw a girl providing sexual relief to her boyfriend (?) on the Bridge on York Road. Eventually the club was moved to the Forum in Kentish Town. I am not averse to drinking and a bit of malarkey - I am know to partake every now and then but it used to be an absolute nightmare!
