When did Paul McCartney’s “Wonderful Christmastime” become such a popular holiday song? I was a big Wings buff when it originally came out (just before Christmas 1979), right as Wings was disappearing and McCartney the Solo Artiste was emerging, so I bought it, played it a couple of times, and that was pretty much that. Looking at the official MPL Communication discography for Sir Paul, it appears that’s what most people did at the time: the single didn’t chart in the UK or the US. But, jeez, I swear I’ve heard that song played more on the radio over the past month than any other song, holiday or otherwise, so it’s obviously grown in the public’s estimation over the years. I wonder how many people realize it’s a Beatle singing it?
