Co-hosted by Professor Owl and Ludwig Von Drake. At the beginning of the program, Professor Owl hosts. When "All in the Golden Afternoon" ends, Ludwig Von Drake takes over as host. Finally, after "Blue Danube Waltz" is over, Professor Owl takes over as host for the rest of the program.
Boo Boo Boo is the only song that doesn't have text words with a Mickey Mouse icon as a "bouncing ball" appearing on the screen, this song has only the blue words with the crooner from A Symposium on Popular Songs bouncing on them.
An edited version of the Old MacDonald Had a Band segment that appeared in this video was credited under Toot, Whisle, Plunk, and Boom. From a technical sense, this is actually correct, becuase it derived from an episode, from the Walt Disney anthology series, titled Toot, Whistle, Plunk, and Boom (season 5, episode 24) that aired on March 27th, 1959. The unaltered version of Old Macdonald Had a Band, which did not appear in this video, appeared instead in the Disney short Jack and Old Mac.
This installment was the first to promote, and feature songs from, a then recently-released Disney film (in this case, Oliver & Company). Prior to this, most installments promoted anniversary re-releases of older films. 101 Notes of Fun was used to promote One Hundred and One Dalmatians in 1994.
Retitled 101 Notes of Fun in the UK and other countries, and was not released until 1994.
†Cruella De Vil appears in 101 Notes of Fun and replaces "Let's All Sing Like the Birdies Sing". It also replaces the reprise of "Why Should I Worry?".
