And a child will lead them.

Here's a clip of what pretty much amounts to science fiction turned fact. Joy on a subway platform. Strangers inspired to shake free of their scowls and stony postures and lose themselves to a moment of wild dance. It's the stuff of myth, an absolute anomaly, and it's all thanks to the infectious happiness of an adorable little girl.

Recorded in November at the Bedford L platform in Williamsburg, Brooklyn, and posted to the YouTube account of married buskers Coyote and Crow, here's a whole bunch of strangers dancing to a cover of the Grateful Dead's "Me And My Uncle."
