Took a walk in the rain over to Water Tower Place this afternoon, to see the “surprise flash mob” performance about which the media were alerted yesterday. If you’ve checked this blog in the last 24 hours, you were alerted, too.

And sure enough, the alerted were in evidence on the second floor of the mall: more than one camera crew, and a bunch of civilians looking around with an air of expectation. Led, probably, by agent provocateurs in their midst, they’d begun to form a ring around what would turn out to be the performance area.

At 2 PM, a pair of beautiful young people met in the middle of the ring and started dancing a sort of 50s modified jitterbug to “Do You Believe in Magic.” Other beautiful kids joined them (severely depleting the beauty in the audience), and by the time they switched to robotic synchrony there was a mob on the dance floor, as anti-advertised.
