I am sure that at least one episode of Keeping Up Appearances has a slightly different opening arrangement where three notes are repeated twice at the beginning before the main theme begins. Does anyone know what episode this is? If so, please let me know, thank you all!
That usually used to happen if there was a very big cast in an episode which made the end credits longer than normal. I don't remember this version being used on the opening.
I am fairly certain they did use the longer theme over the opening titles on at least one episode (unless they have since reedited the episode to use the shorter theme but I do not know why they would do this).
