Sir Paul apparently had just gotten himself a Polymoog and had some studio time laying around, so he threw this together for the season in 1979. It's slapdash and could have been a tad shorter, but other than that it's just fine, even if that is Linda on background vocals. (Linda was a great human being in so many ways, just not much of a singer.) It probably suffers in comparison to John Lennon's "Happy Xmas," but then many Christmas records do, don't they? Nevertheless, the song has notched its fair share of covers over the years as well. The B-side, "Rudolph the Red-Nosed Reggae," is even more slapdash, but then Paul doesn't often get credit for
having a sense of humor.
UPDATE: The single sleeve links you to one of those
Now That's What I Call Christmas discs, since Paul is in the process of taking all of his solo works away from EMI and over to Hear Music, the Starbucks label. There is a
reissue of the original single on red vinyl knocking around out there, though it's out of print as well.
