When you think of The xx covering Christmas, there might be a plethora of random reworks that come to mind. While hearing them redo “Rudolph the Red-Nosed Reindeer” might sound appealing, it makes sense for them to stick with what makes sense. For their “mystery cover” at the BBC Radio 1 Live Lounge, The xx take it back with a cover of Wham’s “Last Christmas,” and it’s just as awesome as you imagine it would be.
