The Two Ronnies

My uncle claims to have made a brief appearance in The Two Ronnies. He says he was in a scene where him and a girl were 'frolicking' in a haystack and were disturbed.
Can anyone shed any light on this? It would be mid to late 70s if that's any assistance.
Thanks.

That could be any number of RB's sketches/films, but Futtocks End rings a bell maybe where there are a couple of scenes that might fit the bill.

There's one similar scene at about 30 minutes, but as I say I think there maybe another one in the same film or here are some more:-
