Strangely, Esther's husband Woody is missing from the holiday gathering at their apartment at the story's ending.
This episode was taped in early November of 1975 .
There's a moment when Lamont refers to the famous nineteenth century book -- A Christmas Carol -- upon which this episode is based, and to which Fred responds, "What the dickens are you talkin' 'bout?", Charles Dickens being the author of the tale.
When Fred tells the Spirit of Christmas Past that he's the Spirit of St Louis, Fred is making a cultural reference to Charles Lindbergh's famous plane of that name in which Lindbergh made history with the first solo trans-Atlantic flight.
This takes place in December 1975.
