The original tv broadcast version of only fools and horses s06e01 (yuppy love). The dvd version available everywhere has a scene cut out where Rodney asks Casandra to dance and it’s so weird without it. I think it was due to copyright on the music playing in the scene
This is actually available on the internet, here’s the note for that episode:
S06 01 - Yuppy Love (Music cuts restored) (TV/DVD/VHS)
There are actually a lot of episodes throughout with music-related cuts judging from the list I’m looking at.
That’s unfortunate! I’ve heard of a similar case with other properties. I’ve heard some time ago that students have access to some version of the entire BBC library but I don’t know the extent of access or quality. There’s many UK shows I’d like to collect but they prove difficult to find still
