Starts a little slow, then all hell breaks loose around 1:15, combining Hee Haw with Cirque.
This is apparently taken from the 1944 MGM musical Broadway Rhythm, which doesn't appear to be out on DVD in any form. Looks like it would be...interesting, to say the least.
Update: Original vid taken down, so the 1:15 time above is way off. But just know it's coming.
