Had the international megahit Wicked been produced in the late 70s, we would love to imagine that two-time Tony winners Bernadette Peters and Patti LuPone would have shared the stage as Glinda and Elphaba, respectively. We can almost hear Peters asking, "It's good to see me, isn't it?" or belting out "Popular," and the thought of LuPone literally soaring with "Defying Gravity" is equally thrilling.
