We just went Saturday in Philadelphia. The line up there was:
4:30 Jake Owen - Awesome show; the stadium was only about 1/4 full and he had the place totally rocking! High energy, very good performance.
5:30 Grace Potter - Not crazy about her show though some seemed to love her. I read during much of her show.
6:30 Tim McGraw - PHENOMENAL show!! Could not have been any better. Very high energy, entertaining, had the filled-to-(concert) capacity-crowd eating out of the palm of his hand.
8:30 Kenny Chesney - Awesome! (Though I thought the sound engineering was not the same high quality as Tim, interestingly enough).
~10:20 Tim McGraw came out and they did 3 songs together-- I think Tim's band and Kenny's were both on stage for most if not all of this segment. Unbelievably good. Truly worth the price of the ticket, and the comaraderie on stage was wonderful to see.
Then, Jake Owen and Grace Potter came out and the four of them did another song. Great!
