Here’s an interesting tidbit I just found on that page - They call it, At the Ball that’s all - perhaps that’s the real name of the dance.

It really makes you appreciate how Ollie just eased into it so naturally, like he was making it up as he went! Me, I'm one of those people who would happily make a fool out of myself dancing for nothing but silliness if the music so inspired! And frequently do when I'm in the kitchen! [^ )
