And you thought you were done with Gangnam Style videos. Not hardly!
Behold the roots of Gangnam dance moves: the Agnes DeMille ballet Rodeo, from 1942. (You’ll get all you need from the first 45 seconds.) Nobody’s saying Psy stole any of his moves from DeMille, but the echoes are interesting. Agnes had fewer explosions, though.
The original video is now over 730 million views, by the way.
