The Merry-Go-Round Broke Down

"The Merry-Go-Round Broke Down" is a song written in 1937 by Cliff Friend and Dave Franklin and published by Harms Inc., New York. It is best known as the theme tune for the "Looney Tunes" cartoon series and "Merrie Melodies" reissued cartoon series produced by Warner Bros. Cartoons, used from 1937 to 1969.
The original version contains an introductory verse that leads up to the main part of the song, as a young man tells of his date with a young woman, in which they go to an amusement park and find time to "spark" while riding the malfunctioning carousel. The name was a play on "breakdown" and the tune is similar to the traditional "Chinese Breakdown" as well as the children's rhyme "Miss Susie had a steamboat".
"Merrie Melodies" and "Looney Tunes".
The tune first appeared in the "Merrie Melodies" cartoon short "Sweet Sioux", released June 26, 1937.
Starting with the "Looney Tunes" cartoon short "Rover's Rival" released October 9, 1937, an adapted instrumental version of the song's main tune became the staple opening and closing credits theme for the "Looney Tunes" series, most memorably featuring Porky Pig stuttering "Th-th-th-that's all, folks!" over the tune at each cartoon's end.
A different vocal version, sung by Mel Blanc (voice of Daffy Duck), was heard in "Daffy Duck and Egghead", a 1938 entry in the "Merrie Melodies" series at about five minutes into the cartoon. Daffy also sang a specially-modified version of the song in the 1950 "Looney Tunes" short "Boobs in the Woods".
The tune also made appearances in the "Merrie Melodies" shorts "Jungle Jitters" (1938) and "Aviation Vacation" (1941). The Three Stooges recorded a version in 1959 for their musical album "The Nonsense Songbook".
In 1963 a new, more dissonant, variation of the theme was arranged by William Lava for use with the updated opening sequences of new "Looney Tunes" and "Merrie Melodies" shorts. In 1967, a remix of the Lava version was used in the opening sequences of new "Looney Tunes" and "Merrie Melodies" shorts.
"Who Framed Roger Rabbit".
The song is used in the film "Who Framed Roger Rabbit" (1988), an animation/live-action blend based upon the cartoons of the 1940s. "The Merry-Go-Round Broke Down" is performed twice in the film: first by cartoon character Roger Rabbit (voiced by Charles Fleischer), as he's being assisted by his human partner Eddie Valiant (Bob Hoskins) in hiding out from Judge Doom's weasel henchmen and later by Valiant himself in Marvin Acme's gag factory, as he's trying to force the same cartoon weasels (after they capture Roger and Jessica) to laugh themselves to death. The lyrics in both sequences were written specifically for the film. Roger's version was released on the soundtrack to the film.
