Just saw a Fidelity Investments commercial broadcast on American Idol, 4-18-07; two women are talking money matters, and over their conversation at the very end a simple but strangely familiar piece of music begins to plays, with flute, snare drum, and piano; it's almost like a march, but I suspect it turns into a popular song or bit of movie music (or maybe it's original). Driving me crazy! Can anyone identify it?
