Man, that kid's pretty darned good! He sure didn't miss a beat.
Buddy Rich simply amazes me. Did you ever see him play against Animal from the Muppets?
In some of his vids, you can see sweat pouring off of him. I wonder what his folks thought of him and his energy when he was a kid.
According to the comments in your video, that wasn't Buddy Rich, but Gene Krupa on the drums. You can also find a "Playoff" video of them together.
