Marks and Spencer brings out some stars

So, Marks and Spencer is airing this somewhat star-studded (is that an oxymoron?) ad to usher in the Christmas season in the U.K. Of course, for those of us stateside, that song, "Most Wonderful Time of the Year" will, strangely, always be associated with that Staples ad from Cliff Freeman and Partners celebrating the start of the school year. Or maybe I just watch too many commercials.
