Thank you for sharing this video with us. It's very interesting. I don't recall seeing the picture of Michael - the one that has the 2010 date on it (around 6:00 mark).
I'm not sure about the girl you point out - I'll need to look at some more pictures. Perhaps she is a fan who was able to go to the shoot. Remember, they took fans that day as well. We had a couple who belong to this forum also go so maybe it's a simple explanation. But, maybe not.
This does give a bunch to think about. Blessings.
