What's shaking? The earth moving under your feet. It's you, smiling, and her holding the door open, and him offering encouragement to his son. Its US, merging from me, you, he and she to WE! Together we raise the vibrations of the planet infinitesimally. What makes the earth move for you? Sing along with Carol, as is, or change lyrics to suit you. Or choose a different song. Whatever you decide, raise your voice high, higher and higher, until you FEEL THE EARTH MOVE!
