For "Maple Leaf Day", an obscure Canadian cousin of Arbor Day, we're celebrating trees. But expect the unexpected - sorry, no Tannenbaums. Instead, we review "Hanukkah Tree" by The Klezmatics, a Klezmer tune with lyrics penned by a famous goy, and a version of "Rockin Around the Christmas Tree" with a poorly-executed plot twist performed by Canadian sensations Michael Bublé and Carly Rae Jepsen.
