Just kidding. The guy, a Frenchman, I believe, who made this video has produced a collection of similar offerings, all with unrelated old movies synced to the beat. His accomplishments are quite remarkable and witty. Peer is right - it is an art form.
I'm just as mad as a hornet. My wife and I paid good money for those Cajun dance lessons and they NEVER showed us how to waltz like that. I feel cheated. Guess she took the Advanced classes. Can you please post one of her doing a two-step? I had better check with my cardiologist be before I watched her zydeco, though.
