7. Imagine you're going about your Christmas shopping and all of the sudden you hear the opening strains of an organ playing the familiar Handel's Messiah. Then, over 600 of your fellow shoppers break out in full part harmony, and you find yourself in the middle of a real, live performance of the Philadelphia Opera Company.
