Here are some naughty soundies:

• 'Who's Yehudi?'
• 'Hawaiian Hula Song'.
• 'Cow-Cow Boogie' with Dorothy Dandridge.

What were soundies? Three-minute music videos in the 1940s. You put a coin in the jukebox and you watched them. They were filmed 'backwards' and projected from the back of the box. Read about them here.

Not all of them were naughty, but hey, you have to keep the buying public interested. Which leads us to burlesque. Burlesque also benefitted from this technology.

• Variety Girls Soundies (1948). Right in the middle, there's a guy tap-dancing. He's really good, even though he keeps all his clothes on. The pianist ain't bad, either.
• Not a Soundie, but a short format film with Sally Rand. Sally Rand was a 'fan dancer'. Click and you'll see why. You know the old joke about the fan dancer who landed in hospital? She was using an electric fan.

Okay, all of this is tame in the internet age. But it's fun to see what turned them on, back in the days when Betty Grable was a pin-up girl.

PS You want a more modern take on this sort of activity? Watch this episode of Stephen Colbert's 'Difference Makers'. Here, Colbert takes up the case of Stephen Dick, who campaigned for a tax break for his exotic dance club in Albany, New York. After all, it's an art form, and therefore not taxable, according to Dick¹.

It's art. Not a kitchen utensil.
