This is Cambridge: Ray Gosling documentary (1974)

Towning Gown. The legendary Ray Gosling (Nottingham Grammar, Univ. of Leicester) visits Cambridge to immerse himself in awkward waters. "Presenter Ray Gosling's sympathies lie with the graduate dustman and café owner, the college bedder and the teddy boys at the Rex Ballroom. The college settings look sublime as university people play croquet and cricket, dine at the all-male Pitt Club, and dance at a May Ball. Ray feels seduced by the glamour of it, but cannot accept the unfairness and privilege. Classic Cambridge college scenes are mixed with landmarks of the 'real' Cambridge and local street eccentrics."
