What does a baby get out of a disco?

Before I had a kid, I thought baby disco parties sounded like a tiny version of hell. A bunch of screaming toddlers and parents trapped in the dark with a mirror ball? Please.

Then I discovered LBZ's love of Jay-Z. And Michael Jackson. And Stevie Wonder. And Shuggie Otis. And then I saw this video and decided I'm going to give it a shot. Have any of you gone to a baby disco? Did you like it?
