“River” - Joni Mitchell
”Glad Tidings” - Van Morrison
“Christmas” - The Who
I’ll give Patti Smith’s version of “O Holy Night” a listen, of course. Perhaps as well, Pavarotti and Domingo’s. And I’m sure to listen to several versions of “The Hanukkah Song” by Adam Sandler.
I second The River. Still gives me chills.
