This Christmas just got a little bit colder. The xx recorded a chilly take of Wham!'s mega-holiday hit "Last Christmas" for BBC 1, with all its vocalists taking turns.

Romy Madley Croft has always had a "ballpark" singing voice, where she doesn't always hit the ascribed note, but it's in the ballpark and it's ever on-base. It works here, a more sultry style than the matter-of-fact as the original had been. Would love to see their take on feathered hair.

Meanwhile, the xx continue to promote their latest album "Coexist" with latest single "Chained" and with a new short film series. The "Coexist Series" can be seen via YouTube, and features an intimate version of "Fiction." Check some of that out below.
