The familiar Looney Tunes theme is based on “The Merry-Go-Round Broke Down,” a song written by Cliff Friend and Dave Franklin and published in 1937. Warner Bros. adopted the melody for Looney Tunes theatrical cartoons, where orchestral arrangements accompanied opening and closing title sequences. Decades of television reruns introduced it to new audiences, while online creators later used short excerpts as comic endings and nostalgic transitions. Its lively melody remains closely associated with fast-paced cartoon humor and classic animation.
