Where did the group tango scene originate?

Y’know, in movies where a whole ballroom full of people (including our Leads) dances a synchronized tango? Generally the Scandalous Lady is wearing red, where everyone else is wearing black and white, but I don’t know if this is always true. I can only remember it in Moulin Rouge! and *Rent *off the top of my head, but it was so “classic” in those two that I’m certain it started long ago. Any ideas?

I don’t know for sure, but I think it might be a matter of logistics. When they play a a tango, it’s probably more convenient for everyone to be doing the same thing in the same direction at the same time, or “tango” turns to “tangle.” :wink:
