Al has already done a couple of very nice recaps from the Paul McCartney concert at Wrigley Field on July 21. 2011.
The scene around Wrigleyville was quite something. I can say with a degree of confidence that the large crowd was the most upbeat I've seen at the ballpark in quite some time. Perhaps knowing they were going to have a good time and not worrying about whether a certain baseball team was going to win or not had something to do with it. A good night was guaranteed.
I've posted some photos below from that night for those interested.
P.S. Thanks to BCBer eths for the headline idea.
