Bang was the name of a popular gay disco which started in 1976 in London. It was held in the Sundown club (in the huge basement of the London Astoria, subsequently called LA2, and now demolished) as a Monday night event called Bang! . Bang later became Funboat (in 1985)  and later still the G-A-Y nightclub. Bang became known as Bangs to regular attenders.
