Jimmy Fallon's elementary school instrument band strikes again! Joining him this time are the studs of One Direction, each wearing their finest Christmas sweaters, and contributing some fine percussion. Louis Tomlinson, Liam Payne and Niall Horan all get maracas of some kind, while Zayn Malik rocks the triangle and Harry Styles gets a drum and a kazoo. All of it adds up to a very charming rendition of "Santa Claus Is Coming to Town." Is it as cute as the Christmas singalong Fallon did two years ago with Mariah Carey singing "All I Want for Christmas Is You," complete with adorable child chorus? For research purposes, we've embedded both videos below, so you'll have to be the judge. We also appreciate the fake fire burning away behind the Roots on a TV monitor to set the mood.
