"Quadrophenia", Phil Daniels, Ray Winstone (1979)

A somewhat goofy but cute scene from this late 70s British drama features two neighboring bathers engaging in a sing-off (though screencaps make it look like they're practicing orgasm faces) while letting it alllll hang out in their bathtubs.

Another fairly well-known "oldie" nude scene that I've rediscovered through a BluRay upgrade!
