Today's Piano Puzzler

This week's contestant is Sara Tillotson from Tulsa, Oklahoma.  At first, I was able to pick out the hidden song by focusing on the proper hand which was playing the tune, though eventually it became perfectly clear without that.  As for the composer style, I didn't have a clue -- the same as the contestant.  To my surprise, my one offbeat guess was bizarrely close.  I wouldn't have ever gotten it, though.  It's tough.  But perhaps you can get the era and type of music.
