I, too, wear socks in bed, but not in the summer.

The Christmas program was a long one, I get tired just thinking about everything we sang.
Several works by Norwegian composer Ola Gjeilo, for instance:
A Spotless Rose
Serenity
The Holly and the Ivy
Ecce Novum (with string quartet)

Then there was
Morten Lauridson's O Magnum Mysterium
Hans Leo Hassler's Verbum Caro Factum Est

and arrangements of
Silent Night ("Still, Still Night")
I'll be Home for Christmas
There's No Place like Home for the HOlidays
A Charlie Brown Christmas (Peanuts)

That's all I can retrieve out of the post-COVID memory recall.
