These commercials have been around for several months, but no one I know can identify the ending music. It's just a simple sequence of piano chords behind someone whistling a jaunty little tune. I've heard the sequence of chords before (on a piece by an obscure Italian singer named Paolo Conte), but not the whistled tune; and the chord sequence is simple enough that it's probably been used many times. Anyone have a clue where this music comes from? Thanks!
