Press photos by Lori PatrickHall and Oates perform their hit songs on Sunday at The Great Allentown Fair. One of those songs, “Adult Education” was written by Darryl Hall as an ode to his high school days at Pottstown's Owen J. Roberts HS. The eight-member band opened with “Man-Eater.” The show rounded out a week of acts that fortunately had no rain, making it comfortable for the outdoor venue.
