G-A-Y is a gay nightclub in London. It operated from the London Astoria music venue for 15 years until July 2008. The Boston Globe described it as "London's largest gay-themed club night", NME reported that it "attracts 6,000 clubbers each week", and The Independent described it as "the one London gig that really matters" for "today's pop stars". On Friday 3 October 2008, it moved to famous gay venue Heaven.
G-A-Y is associated with G-A-Y Bar and G-A-Y Late, both of which were also owned by Mean Fiddler Holdings Limited and operate in Soho. The two bars sell discounted tickets to weekend performances, and are locations in which flyer boys operate. The brand was purchased on 13 August 2007 by the MAMA Group. Saturday nights at G-A-Y have seen many performances from a wide selection of artists and genres. Acts to have appeared in the G-A-Y include:
