im looking for the exact same routine for the dance that was played in the movie "Take the Lead" when Antonio Banderas was dancing with the black dressed lady to persuade the students... what is the name of that dance? is it a international tango or a american tango? and where can i find the same exact music that was played in that dance?
Just from memory i saw an interview with Antonio Banderas on the film. He said something about doing that routine a thousand times on the stage in some stage play he was in. It was not an Internation Tango. I`m pretty sure it was Argentine.
I don't know about American tango, but i can definitely say that it is neither international ballroom tango, nor tango argentino (although the choreography is remotely mimicking some movements seen in tango shows, a style called sometimes "tango fantasía", yet done using an entirely different technique here).
I suppose that this is simply an ecclectic piece of choreography, using elements from different genres mainly for effect (the movie character wants to impress the students) and as a framework for the acting. Of course, it is possible that an actual tango style like this exists somewhere.
The song is sung by Veronica Verdier and called "Así se baila el tango", which is actually a quote from a different, very famous traditional tango (which you can find at http://www.carriechelsea.com/songs/asi.html with music to listen, the lyrics and a translation).
