I haven’t seen this 1975 TV film by Mike Leigh, made for the BBC, but I’m told it’s one of his most popular comedies in England. It concerns a couple (Roger Sloman and Alison Steadman) camping in Dorset and their encounters with a phys-ed teacher (Anthony O’Donnell) and a biker couple. On the same program, Leigh’s five-minute A Light Snack, made the same year.
