Yes, of course I looked at those, and lots of even older cinema footage. I raised this number because it's never mentioned, and its elements are more interwoven. I knew it would make some heads explode. I appreciate your allowing that I made useful points. Once again, my focus isn't intentionality, or to project a sociopolitical agenda (or lack thereof) onto the creators; it's the origin of the presentation and dance language. I do believe it's a valid set of observations.
