Name that tune!

Laurie alerted me to this wall in the neighborhood - someone has chalked a musical score on it. Can you figure out the tune? (I believe the first note in the treble clef is wrong, or it's an arrangement I haven't heard.)

Now that my classes are over, I feel a little untethered. My calendar looks so blank! Who knows, maybe I'll get back to commenting on Blip journals! Wouldn't that be nice?
