I love this video. A couple of students at the University of Quebec at Montreal came up with the concepts for it over a few weeks at the end of summer. During frosh week, they recruited fellow students via Facebook and told them little more than to learn 'I Gotta Feeling' and show up at a given day and time. In the end about 174 people were involved, many of them strangers to each other. In just a little over two hours they got the scoop, did a couple of rehearsals, a practice take and the final one linked here. No editing and no cuts. I think they did a fantastic job. It's gone viral (hopefully it hasn't already showed up here!), and deservedly so.
Glad you guys enjoyed it. :) It makes me happy every time I watch it. Anybody that can make that song bearable has done something special.
It will be a fantastic memory for all involved. The university could not have spent a million dollars and matched the recruitment power of that one video.
