Here is a very rare short film from 1937 called Phony Boy with Cass Daly. There are 3 couples that are dancing Collegiate Shag at the beginning of the short. The couple in the white jacket in the center of the dance floor is John and Ruth Englert the 1937 Harvest Moon Collegiate Shag dance champions. The couple on the left of the screen is Virginia Hart and William Ledger. The 3rd couple on the right of the screen is believed to be Joan and Gene Biggins.
