I have only just seen this film on an obscure satellite channel. Way ahead of its time. It would not be out of place if it were remade today (without the awful version of "Livin' Doll"!) Does anyone know who played the youths in the film (apart from Cliff Richard and Andrew Ray) One looked like Nanette Newman and another like Bryan Forbes but they are not mentioned on this site. If it is them perhaps this film is where they met and fell in love.
One thing that struck me as I watched the film is that 46 years on nothing has changed, at least not for the better. A sad indictment on our society.
