Today's Piano Puzzler

This week's contestant is Heather Christensen from Portales, New Mexico. I've gotten pretty sloppy on the composer style lately, but happily -- though I had a few thoughts on various possibilites-- I settled on one and got it this time..The tune though was well-hidden, though you can hear where it's supposed to be. As it turns out, I didn't know the song at all, and neither did the contestant.  So, that will be a challenge for most, I think.  And if you get it...hat's off.
