On the waterfront at the gorgeous Pavilion in Camden, one can revel in the bliss of one of America’s greatest rockers, John Fogerty. George Thorogood will rock the blues as his opening act and, before George, Hearty Har, led by John’s two sons, Shane and Tyler Fogerty—augmented by bass, drums, guitar and keyboards—will start the show before serving as their dad’s back-up band.
