There is a song playing Monty Python's Flying Circus Series 2 Episode 5: "Live from the Grill - O -Mat" during the Teddy-Neddy animation. This occurs at around 19 minutes into the show. It is at 19:14 in the video in this link. (19:17 in the version on Netflix). I like the song, but absolutely have no idea. Recognition software is not working on this.
Any identification would be helpful, or even a genre or direction. If there is more information it would be useful to provide, let me know.
