Back in 1996, CBS produced a TV musical, Mrs. Santa Claus, that starred Angela Lansbury with a score by Jerry Herman (who had written two Broadway shows Lansbury had starred in, Mame and Dear World). It has a charming score, though not many videos of them are available. But here's the audio of the title song, at the very least.
One video that is available, though, is the song "Avenue A." It's not a Christmas song, however -- though it's the big production number and very enjoyable. Angela Lansbury doesn't sing in it -- her character has just landed in New York City, and she's shown around the polyglot neighborhood by a young man played by David Norona. One little tidbit to mention: at the 3:10 mark there's a brief shot of a gentlemen in a big mustache playing a piano in an upstairs parlor -- that's a cameo of songwriter Jerry Herman.
Robert J. Elisberg is a political commentator, screenwriter, novelist, tech writer and also some other things that I just tend to keep forgetting.
