Today's Piano Puzzler

This week's contestant is Jessie Marshall from Jacksonville, Florida.  I was pretty sure I could hear get the hidden song fairly quickly, but it turns out I was wrong.  It has a lot of similarities (let's just say they have the same heritage), but I stopped as I soon as I thought I had it.  But the song is pretty well-known, so others might be able to get it.  It was also easy to get the style of the hidden composer, but alas I couldn't nail it down to who.  And I should have, because I like the guy.  So, I suspect others will do far better than me this week.
