2015 Countdown to Christmas: Baby it's cold outside

10th day of Christmas: Michael Buble and Idina Menzel lend their voices to this darling music video...designed like an old-school '30s film musical number, the video’s charm stems from the all-kid cast, the central couple outfitted in vintage tux and ball gown as they lip-sync Menzel and Buble’s parts while taking on Lynne Page’s nifty choreography through a swanky hotel’s lobby, and briefly meet their real-world counterparts in mirror images.  fun stuff, fun song!
