The best I can date this is around 1977 to 1978, after the release of "Come Play With Me" but before the star's death -- however, the biggest attraction in London for pervs like me wasn't the movie: the UK magazine New Action MS had these ads for "topless massage," assumedly with a happy ending (so to speak). The ads are quite detailed and explicit, as opposed to the entendre-laden all-text personal ads that advertise naughty massage today. Nicole Sauna is the only one still partaking in toplessness, now called Rio's, and New Park Sauna gave up the toplessness to became the Manor Park Sauna; the rest have closed and moved on.
