Starbucks and Barneys New York's store windows may have lead you to believe otherwise, but it's not really holiday season until we hear, "Do They Know It's Christmas?" And while we'll always love Band Aid's original 1984 version, the new rendition, in honor of its 30th anniversary, is a who's who of British music. The all-star line-up includes Rita Ora, Sam Smith, Ed Sheeran, One Direction, Chris Martin, Ellie Goulding, Paloma Faith, Jessica Ware, Disclosure, Emeli Sandé, Sinead O'Connor, and more. The song debuted last night on X-Factor in the U.K. and was recorded at Notting Hill's Sarm Studios, the same studio where the original came to be. This time around, the charity single will benefit the prevention and treatment of Ebola in West Africa. You can make donations on the Band Aid 30 website.
