Beaker -- That would be wonderful!!! Perhaps he will do it as a "surprise" song. I'm always hoping for an extra special song for Philly -- I hope he's able to do a surprise song for us there.
A little bit of trivia here -- the Wells Fargo Arena is actually built on the site of the JFK Stadium that used to stand there -- PG played Amnesty International Show there (at JFK Stadium) and did In Your Eyes with Youssou! I am secretly hoping that will happen here in this show -- how cool would that be, huh?

Also, since JFK Stadium was an open venue and sound travels some distances, at the time of the show (which I attended), my mom told me that she could hear a very, very faint roaring from the crowd that night (during Biko, I'm sure!) -- the house was @ 2-3 miles from JFK Stadium.
