The Dean Martin Christmas Show (December 21, 1972).

NOTE: YouTube didn't allow me to place the corresponding original performances from the musical "Till The Clouds Roll By", so these are missing, as well as a performance from Lynn Anderson.

Musical numbers:
Dean Martin and The Golddiggers – " A Marshmallow World".
Dean Martin and The Golddiggers – Medley consisting of snippets of many songs, and ending in a big finish with "Style".
Dean Martin and Lynn Anderson – Medley: "This Old House" and "You'd Be So Nice To Come Home To".
Dean Martin – "I'll Be Home For Christmas".
Movies Finale pays musical tribute to "Till The Clouds Roll By" (1947).

Comedy includes:
Dom DeLuise and Lynn Anderson play a bickering Mr. and Mrs. Claus. After spending the night on the town, Santa comes home to his angry wife...
