From the Broadway show "Wicked," a take on "The Wizard of Oz" from the witches' point of view, this is a tender, expressive ballad with touching lyrics:"Like a comet pulled from orbit as it passes a sun. Like a stream that meets a boulder halfway through the wood. Who can say if I've been changed for the better because I knew you, I have been changed for good." Its message about how we can affect each other's lives is one your students will easily relate to, and it will inspire them to sing their best in performance!
