Lincoln Financial Field was sold out Saturday for the Kenny Chesney concert.
Among the guests was Eagles coach Andy Reid.
Reid, wearing his usual Hawaiian shirt, headed on stage before Chesney performed "Boys of Fall" to loud cheers and presented Chesney with an autographed Eagles helmet. Reid then pointed as if he wanted to swap the helmet for Chensey's cowboy hat. Cheney obliged and the two stood arm in arm for a moment and saluted the crowd, with Chesney ins an Eagles helmet and Reid in a cowboy hat.
Chesney, sporting a Phillies hat, then performed the song wearing the helmet. "Boy of Fall" was part of the soundtrack for a documentary that Chesney made about high school football players.
