Radio City Music Hall

When Bolero was on the program the Rockettes did double duty.

As admittedly I never saw it from what I’ve read I believe they were used to supplement the ballet company so as the music built to it’s overwhelming crescendo the stage would be filled with more and more dancers so from a company of 28 then with added men(that I’ve seen from pictures) and the additional 36 Rockettes the stage would be a mass of swirling dancers. I’ve also read that men would be beating drums on the choral stairs. Which is why as you noted it was repeated again only months after its initial success. That set is really something and Minnelli might have had a hand in developing it as he was working at the Hall at the time before he moved to Broadway. The use of the reds, oranges and blacks certainly demonstrate his eye for color.
