Dunno where it came from, guess it’s just the season.
mmm
About 2 years ago someone on Twitter mentioned that “Love Shack” was the worst earworm of all time.
I said “nuh uh” and started singing it, and, well, that’s how that happened.
I get lots of other ones too but that’s the main infestation.
For about 2 days I’ve had the opening descending guitar line from Southern Culture on the Skids’ '69 El Camino stuck in my head.
Rust Never Sleeps.
Sunset grill,
My ear worms often start from a phrase I’ve heard or said. I just said “Meanwhile have another beer” Down at the sunset grill. 
and it’s off and running.
The theme from Leave it to Beaver, which I’ve taken to enjoying in the mornings during the time I used to commute. It is a pleasant diversion from the news.
Also, the Chieftains with Alison Krause Molly Ban, a haunting melody: The Chieftains & Alison Krauss - Molly Ban - YouTube
So, today I was surprised to find out that Dr. Buzzard’s Original Savannah Band (Cherchez La Femme) and Kid Creole and the Coconuts were not at all affiliated. But then, after further research, I was not surprised to find that they were both founded or co-founded by the same guy under a different name. The same guy was also in Machine (There But For The Grace of God Go I). In the course of finding out all of this old news from very old bands, I got Endicott stuck in my head. Here, let it stick in your head too:
And it is of course one of the many tunes that’s in ballad meter (8.6.8.6) so you can sing the lyrics of Amazing Grace, Tangled Up in Blue, or dozens of other ballad meter songs to that tune.
For the last two days, it’s been - The Angels Cried by Alan Jackson & Alison Krauss. It’s a beautiful Christmas song that I listened to 2 days ago. Now that’s all I can hear.
Thanks to that Broadway benefit on NBC last night, I’m very sorry to say I woke up this morning with “You Oughta Know” stuck in my head.
It’s not a whole song. It’s just a couple of lines from Midnight Star by Weird Al.
"Eat jelly doughnuts and loose twenty pounds a day.
Hear the story of the man born without a head . . . " The a pause, until I think it’s gone and it repeats.
Pomp and Circumstance March No1
Some monster wrote “S.W.A.K” on the back of a Christmas card envelope meant for someone else but delivered to us by mistake. Now Brian Hyland is in my head and I can’t get him out.
“What Child Is This?” because I’ve been practicing it endlessly on the piano.
I dunno, Mustard, sounds like, “Greensleeves,” to me. 
Roxette’s Some Other Summer, because it seems to fit well with being in a pandemic at the stage where the vaccine is being released.
Yeah, but Greensleeves sounds too…snotty.
mmm
Supertramp’s “Goodbye Stranger”
Oh, that’s going in the act!
(My wife, the piano teacher, chuckled.) 
Of all things, " Ob-La-Di, Ob-La-Da".
Strange.
