[EX Q]: Passage: Cantor appears in caricature form in numerous Looney Tunes cartoons produced for Warner Bros., although he was often voiced by an imitator. Beginning with I Like Mountain Music (1933), other animated Cantor cameos include Shuffle Off to Buffalo (Harman-Ising, 1933) and Billboard Frolics (Friz Freleng, 1935). Eddie Cantor is one of the four "down on their luck" stars (along with Bing Crosby, Al Jolson, and Jack Benny) snubbed by Elmer Fudd in What's Up, Doc? (Bob McKimson, 1950). In Farm Frolics (Bob Clampett, 1941), a horse, asked by the narrator to "do a canter", promptly launches into a singing, dancing, eye-rolling impression. The Cantor gag that got the most mileage, however, was his oft-repeated wish for a son after five famous daughters. Slap-Happy Pappy (Clampett, 1940) features an "Eddie Cackler" rooster that wants a boy, to little avail. Other references can be found in Baby Bottleneck (Clampett, 1946) and Circus Today (Tex Avery, 1940). In Merrie Melodies, The Coo-Coo Nut Grove Cantor's many daughters are referenced by a group of singing quintuplet girls. In Porky's Naughty Nephew (Clampett, 1938) a swimming Cantor gleefully adopts a "buoy". An animated Cantor also appears prominently in Walt Disney's "Mother Goose Goes Hollywood" (Wilfred Jackson, 1938) as Little Jack Horner, who sings "Sing a Song of Sixpence".
Link Information: none Question: Has anyone else sung the song Cantor sang in 1938 as an animated character?
[EX A]: Answer: none
