A Great Demonstration of Collegiate Shag from 1937 (Phony Boy)

Whenever I am doing a presentation and I need to illustrate "Collegiate Shag" this is my go to clip. I haven't found another that so clearly shows the essence of the dance - and I love it when the people in a clip tell you what dance they're doing, just so there's no confusion. It's from the soundie short "Phony Boy" from 1937.
