I recently came across something I had no idea existed: on what looks to be a Christmas episode of a variety show, Werner Klemperer and John Banner performed Silent Night. Or, since they’re singing it in the original German, perhaps I should say, Stille Nacht, heilige Nacht.

For those who don’t know, Klemperer and Banner are best known for playing Colonel Klink and Sergeant Schultz on the TV show Hogan’s Heroes. (In real life Klemperer was a German Jew whose family left Germany in the 1930s and Banner was an Austrian Jew who left Austria and came to America when Germany annexed Austria.)

I knew that Werner Klemperer sang, but I didn’t know that John Banner did. Their voices work well together; Klemperer is a tenor while Banner seems to be a bass. It’s quite pretty.

(After this performance, Robert Clary, who played the French POW Louis LeBeau on Hogan’s Heroes, sings a French Christmas Carol, which is interesting, though I don’t find it as interesting as the duet.)
