Today's Piano Puzzler

This week's contestant is Sarah Painting from South Hadley, Massachusetts. I got the hidden song pretty quickly, which is a good thing because it gets pretty well-hidden further on.  As for the composer style, I could make out a particular quote but just couldn't put the name to the music -- which is a shame because he was the first name I came up with and then veered away to someone else.  Silly me.
