Do Re Mi - Train Station Improv

How cool is this? This reminds me of a modern-day musical when everyone suddenly knows all the words to a song and choreographed moves to go with it!

I have fond memories of beginner piano lessons. This was actually the first piece I ever learned to play, using both hands. I recall practicing into the wee hours of the night, much to the dismay of my family, who even to this day cannot hear the intro without cringing, "NOOOOOOOOOOOOOOOOOOOOO!!!!!!!!!!!!!!!!!!" ;-)
