Today's Piano Puzzler

This week's contestant is Wiley Newbold from Morgantown, West Virginia.  It's a very lovely piece, and the style will be familiar, though I wasn't able to get the specific composer.  And I had not idea what the hiddden song was, even though it turned out to be well-known enough.  Even knowing what the song was, I had a hard time picking it out when Bruce Adolph played it through a second time, though I could hear the sensibility.
