Thanks much for your info. Does anyone have any other thoughts, ideas?

at 3:30, at the very end,

No, but you'll foind it at the end of the dance number that Bob Hope and James Cagney perform imn the "Seven Little Foys'.

What is the significance of the fingertip fanning that is done at the top of one's head while dancing in old movies? I have seen this done by Danny Kaye in "White Christmas", Fred Astair in" Holiday Inn" and Bob Hope and James Cagney in the "Seven Little Foys"?
