In case you didn't know, certain subway trains play a three-note phrase from the West Side Story song "Somewhere." It's a fascinating phenomenon to hear "There's a place..." though I wish the timbre weren't so close to the sound of chalk on a blackboard.
Traces of West Side Story turn up elsewhere, too. People have noted that Danny Elfman's theme song for The Simpsons starts with the three-note "Maria" progression, except that the words are "The Simpsons."
But I'm not sure anyone hears the other West Side Story notes that I hear in the theme to The Simpsons. So the first person to identify that West Side Story "source" song and musical phrase gets a point.
Anyone can play. Leave your guesses in the comments section, using a distinct moniker so you aren't confused with the other players, such as Debbie and Deborah.
