I was intrigued to read what Emily considers to be the worst Christmas song ever written. Now I must confess I've never heard "The Christmas Shoes", but I do concur with her where it concerns "Last Christmas" regardless of who sings it. I also haven't heard Céline Dion's version of "Feliz Navidad" and am inclined to avoid it despite having recently read Carl Wilson's treatise on bad taste concerning her album Let's Talk About Love.
But I must part company with Emily when she includes John Lennon's "Happy X-Mas (War is Over)" and Paul McCartney's "Wonderful Christmas Time". I included both of them in my list of my twelve favorite Christmas songs several years ago.
