Ann Miller tap dances her way through the number "Prehistoric Man," from the film "On the Town." The clip also features Gene Kelly, Frank Sinatra, Jules Munchin, and Betty Garrett.
Fred Astaire sings "Fated to be Mated" from the film Silk Stockings. And then he and Cyd Charisse dance. And then dance some more. And then some more. It's a lot of dancing, folks.
