I can only guess... in that really wide shot at 1:08, there is a soft top light over the center -- the trickier part isn't figuring out the light on the people, it's the uplighting on the second floor arches, as if were lit from the glow of the candelabra floor lamps. I think there are a lot of hidden strip lights (maybe LED strips) all around to uplight the ceilings and arches.
As for the center soft top lighting, it changes from shot to shot, sometimes only the back row of dancers are top-lit and the foreground is light with another lower light. So I'm going to make a guess and say that the set was lit with a ring of hanging space lights, and then the center of the ring is filled with another space light, or a couple, all probably skirted, and they are turning some off and on depending on the shot (and raising and lowering them.)
It's possible that they are using a balloon light for the center overhead so that they can drag it around, lowering it for the closer shots so that it is just over the lens.
If you're not sure what a space light is, search under "6K space light" -- here is one page with a photo of some:
But I'm just guessing.
