For those who enjoy dancing, the sort of thing you saw in That's Entertainment. Someone put together a bunch of clips of dancing from movies to the Pointer Sisters singing I'm so excited. A few comments in, someone went to the trouble of identifying each one. There are clips of Kelly, Astaire, Sammy Davis, Jr., the Nicholas Brothers, and many, many, more.
If you enjoy watching dance, worth the watch. The title says Movie Stars, but it's almost all dancers.
