1920s Fox Trot and Waltz - Dance Scenes from "Regent Hall".

I happened on this fragment of an obscure British film set in a dance hall that contains a lot of nice detail. I also love it when they put up a sign saying "Fox Trot" or "Waltz" to remove any doubt. I am a bit disappointed they flashed a One Step sign, but didn't show it. I am curious what a British One Step would look like given how One-Steppy their Fox Trots are. You would seldom see a dance called a One Step in the States by this time.
