Accompanied by just a piano, Smith expertly croons his way through the sad tune for a simple, no-frills -- dare we say, haunting -- rendition of the Christmas staple and even cracks a smile at the end of the performance.

At the GRAMMYs, the soulful "Stay With Me" singer will go up against the likes of Taylor Swift, Iggy Azalea, Pharrell Williams, Beyonce and Meghan Trainor in the top GRAMMY categories, including Album, Record and Song of the Year.

Earlier this month he dropped by The Ellen Show to talk about his decision to publicly come out as gay just prior to the May release of his album, In the Lonely Hour.
