Best "flash-mob" version so far, by far.
If you want to get critical, the singers in the food court were disconnected, a couple of them were off time and off pitch, and the tone and delivery was way too operatic for baroque music.
The Philadelphia Opera did a much better job over at Macy's,here. Of course they have that wonderful Wanamaker's organ.
At least the kids used Robert Shaw and the Atlanta Symphony.
