From the December 21, 1976 episode of Laverne & Shirley, “Christmas at the Booby Hatch” or “Oh Hear the Angels’ Voices.”

Featuring Michael McKean (Lenny) and David L. Lander (Squiggy). I don’t think I saw it 40 years ago — I only watched the show intermittently — but nothing every really goes away on the Internet.

Next, “Ríu Ríu Chíu,” as sung by the Monkees on their show on Christmas Day 1967.

I’m pretty sure I didn’t see that when originally shown either. But it was an inspired choice for the Prefab Four.

Finally, something not about Christmas: “Sailing to Philadelphia” (2000), sung by Mark Knopfler and James Taylor. It’s about Jeremiah Dixon and Charles Mason.

We are sailing to Philadelphia
A world away from the coaly Tyne
Sailing to Philadelphia
To draw the line
The Mason-Dixon Line

Just how many songs are there about the Mason-Dixon Line? One, anyway. I happened across it not long ago. A delightful discovery.
