Potato Salad ? in winter

Here is a little movie movie clip from 1944, the Ross Sisters.

Nobody knows them. (Ignore the first 45-60 seconds of music as it's nothing special, but what follows is fantastic. This was passed onto me and what they can do with their bodies - hummm - reminds me of the modern day Chinese acrobatic artists and the flexible bodies some of these younger girls have.
