It looks as if they've taken a page from the social media especially YouTube. They appear to have the right goal in mind with getting as much social participation as they can in hopes of a viral campaign. But I am very suspect that the UGC is staged, but I can't confirm that right now.

KFC has put together 9 commercials with amateur videos of "customers" putting up a song and dance. I must say it is a genuine effort, and some of these may end up on YouTube: the exact people they want to target.

I don't want to judge this campaign too early, but it looks to me like it's going to miss the social media and viral effect and just end up with a couple of votes from a YouTube generation.
