Ever wonder why you can't get a seat in the mall food court?

I will admit this is a clever stunt that took a lot of preparation. While watching it, however, I kept wondering how many camera operators were used and whether it was all done in one take. I doubt it was done just once because, with all the different camera angles displayed you never see another photographer in the video (except, of course, those shooting with their mobile devices and the quality of this video is too good to be shot with a mobile phone.)

Thanks to My Hero for alerting me to this video and, if anyone knows where this took place and especially the name of the choir, please let the rest of us know in the comments section.
