The scene showed in the vid of the post above is Fred Astaire and Eleanor Powell dancing to Begin the Beguine from Broadway Melody of 1940.
Here is the whole dance to the original music.
There is a bit of an introductory scene in this clip from the movie. I have attempted to start it when Astaire and Powell come out but if that didn't work,
just go to 59 second point and start there.
Little known fact is that Astaire did not very much with Powell and went on to dance with other ladies (Ginger Rogers and Cyd Charisse and others) because....well, he was intimidated by Powell's dancing. He said “Eleanor Powell, one of our greatest talents, is a bit too powerful for me,” he said. “I love Eleanor Powell, but she dances like a man." Really, she was the only one who could meet or even out dance Astaire. In some lists of best tap dancers ever, she is often ranked higher than Astaire or Gene Kelly (

This is an interesting write up about Powell, the reaction of her insecure male co-stars (incl Astaire), and how this killed her movie career.
Eleanor Powell, the magnificently talented movie-musical performer of the mid-twentieth century, was too good for Hollywood. I don’t mean too virtuous; I mean too virtuosic—too masterful at her specialty, tap dancing, for the powers of the studio system, including its powerful male stars, to...

Keep in mind, Astaire was a brilliant artist....but Powell did it in heels and the torture devices that was ladies under garments at the time. IMO, Powell wins by a landslide! haha
Also, there is part of this dance where the music stops and they keep dancing. My hearing isn't that good but all I hear is one dancer. They were THAT syncopated and in time with each other. See if you can hear two dancers or only one.
To me, this is one of the greatest tap dance scenes ever recorded. Its brutally hard work with a great deal of effort made to look like there is no effort at all.
I just love this stuff.
