Today's Piano Puzzler

This week's contestant is Jim Hanson from St. Paul, Minnesota,  It's a short, fun piece -- and I didn't get any of it.  And my teeth were chattering enough because so much sounded familiar that i felt I should get both the hidden song and composer style.  It turns out that while I do indeed know the song quite well, it isn't one that I know as wildly-familiarly as I thought.  To the contestant's great credit, he guesses it -- so it is gettable.
