There was a TV programme in the UK recently in which the former ballerina Darcey Bussell danced 4 dances from musicals- Puttin on the Ritz, Cheek to Cheek, an updated dance based on Cyd Charisse in The Band Wagon, and Good Mornin from Singin in the Rain. Puttin on the Rizt should be in the space capsule to show aliens what earthlings can do. You may find my list The Very Best of Fred Astaire of interest, just a pity a couple of his best dances with Ginger aren't on youtube but plenty of others to admire
