A new movie is out for those of you  who think orgy facility documentaries are fascinating: 
American Swing documents Plato's  Retreat, a swinger's club in New York during the late '70s disco days, largely relying on an interview with the proprietor before his death in 1999.  I know of Plato's Retreat from some  history-channel / VH1 / discovery-channel quasi-documentary, which spent most of its time recapping after frequent commercial breaks, but it was intriguing enough that a documentary 
just on  Plato's could definitely be a viewport into that 'free love' era of recent time; double-bill it with 
Inside Deep Throat, and you've got a night of seventies sexual nostalgia.
