Today's Piano Puzzler

This week's contestant is Caroline Cassil from Sutherlin, Oregon.  If you don't get the composer style within three seconds (and the specific piece it's based on), you're not trying.  The hidden song is tougher.  Until halfway through, when a passage leaps out.  But they're very well interwoven, so you have to catch the passage.  There's also a wonderful musical joke between the classical piece and the hidden tune.
