Julie Andrews and Rowlf the Dog on the piano sing "I'm Old Fashioned" in Julie Andrews: One Step Into Spring. Their duet comes after a brief banter with Gonzo, Miss Piggy, Scooter and Floyd about their comedy sketch having been cut from the show. When the song is finished, Rowlf reflects on the lyrics and is relieved to know that there's someone who's more square than he is.
