If you like dancing, you’ve probably got a gay man to thank. That’s the contention – convincingly borne out by some fabulously sweaty disco archive – of Queer as Pop, the story of how, time and again, music has filtered from the gay scene to the mainstream. The rise of disco, the death of disco, house, hi-NRG, the Village People and the moment when David Bowie put his arm round Mick Ronson on Top of the Pops: it’s all here. This documentary reveals how the social and political liberation of homosexual men has influenced the music mainstream over the past 40 years.
