You'll Adore This A Cappella Take on "All I Want For Christmas Is You"

This all-male a cappella version of Mariah Carey's Christmas hit may just be your favorite holiday song this year. Oxford University's a cappella group Out of the Blue released an incredible cover of "All I Want For Christmas Is You," and not only is the video beautiful, but all proceeds from purchases of the single will be going to charity. In the video, which was filmed at the university's iconic Bodleian Library and Divinity School, the guys sing, dance, and get seriously festive, holiday sweaters and all.
