You are a college student.  You go to see Billy Joel perform on campus.  He was a childhood idol. You also happen to play the piano.  You raise your hand during the Q&A section.  He calls on you.  You ask if you can play your favorite song with him.  He agrees.  The rest is history.  As this student describes it: “The greatest moment of my life.”   Sit back and enjoy…this is something special.
