Not my favorite Christmas song, old or new(ish), not by a long shot. But I don’t particularly mind it.
Wow, I have never actually heard (or seen) that before, And I’m a big Beatles fan. The mind boggles.
If you’ve ever had your anus NOT prosper, you’d better appreciate the sentiment.
5 years later and I am glad, nay, thrilled to report that I have avoided this song for this entire season!
Also, I have grown fond of the theory that this isn’t really a Christmas song, but an interrupted Satanic ritual:
The mood is right
The spirit’s up
We’re here tonight
And that’s enough
(grandma enters the room)
SIMPLY HAVING A WONDERFUL CHRISTMAS TIME!
(She leaves)
The party’s on
The feeling’s here
That only comes
This time of year
(She re-enters)
SIMPLY HAVING A WONDERFUL CHRISTMAS TIME!
(Repeat as needed…)
McCartney and Lennon are both legendary songwriters who have made significant contributions to the world of music.
McCartney wrote many great songs, most of them upbeat, some overly sweet. Lennon wrote many great songs too, most of them gritty, some overly caustic.
I liken McCartney to Mozart, a born musical prodigy and gifted songwriter, who wrote mostly ornate, beautiful compositions. On the other hand, I liken Lennon to Beethoven, a self-made virtuoso and gifted songwriter, who wrote raw, emotional, dramatic compositions.
I love Mozart, but prefer Beethoven.
Wonderful Christmastime is one of McCartney’s overly sweet clunkers.
Mull of Kintyre was number 1 in the UK charts for 9 weeks around
christmas 1977. That really was dreck. But not a ‘christmas’ song per se.
(Nigel Tufnel voice): “Well, that’s just nitpicking, innit?”
The key here is simply, the song is meant to convey a simple message. Brilliant!
I don’t know who this 2018 pulykamell is, but “Wonderful Christmastime” is my most hated Xmas song ever now. I have stopped drinking since November 2020, so perhaps that has something to do with it. 
Seriously, I used to like this song? Huh?
It’s an OK if uninspired 1:50 song squeezed into a 3:45 track length.
It’s up there with “Why Can’t We Be Friends” for choruses that wear out their welcome the quickest and stay the longest.
It’s not even the laziest Christmas song sung by McCartney. That would be the Beatles’ Christmastime Is Here Again.
I heard Redbone’s Come And Get Your Love this morning and thought of this thread. They have a lot of contenders for laziest song, but I think this one takes the cake.
