I have a treat for you today, since it’s Friday. Alicia Keys hasn’t (as far as I’ve been able to find out) written a Christmas song but she has sung a bunch of them, including a version of John Lennon and Yoko Ono’s Happy Christmas (War Is Over) with Tim McGraw, which was nearly today’s song. But then I thought, if we’re going to allow duets with men (and we are; for reasons that should be dazzlingly obvious if you are a fan of Christmas music and brilliant women singer-songwriters) then we should also allow duets with muppets, because muppets are super Christmassy and everyone loves them. So here to send you on your Friday with gladness in your heart are Alicia and Elmo with one of the very best carols of all.
