Ko-Ko Song Car-Tunes, Song Car-Tunes, or (some sources erroneously say) Sound Car-Tunes, is a series of short three minute animation films produced by Max Fleischer and Dave Fleischer between May 1924 and September 1927, pioneering the use of the "Follow the Bouncing Ball" device used to lead audiences in theater sing-alongs. The Song Car-Tunes were also pioneer efforts in the first application of sound and animation, years before Paul Terry`s Dinner Time (released October 1928) and Walt Disney`s Steamboat Willie (November 1928).
