http://www.youtube.com/watch?v=RsvKdoNMVqoI saw a different video of this on the news today. Apparently these are being done all over the world. It's kind of fun. As a side note, there were a couple of police officers and one government minister in the dance. I don't think they rehearsed(they did). You'll want to watch this fulscreen as the video isn't too good. If I find a better video I'll post the link...
Not really a better video but a different location. The group did this in four different Montreal locations today...
