Here’s some good shit. This 2-minute+ film is called Yoga Dancing 1956, and features Prima Ballerina* Madame Legat and her charges at the Legat School of Ballet, in Tunbridge Wells, Kent. It is narrated by a smirky cat with a highball in his hand. Dig!
*this word is real!
Madame Legat, um, assists a young lady.
