Watson also provided the (uncredited) voice for Prince Chawmin' in the cartoon Coal Black and de Sebben Dwarfs (directed by Bob Clampett, 1943), one of the racially objectionable Censored Eleven; primary voice artist Mel Blanc's contract only allowed for his solo credit. In a 1969 Funnyworld interview conducted by Michael Barrier and Milton Gray, Bob Clampett recalled Watson's name erroneously as Zoot Watson; thus, Leo Watson himself went uncredited for his work in the cartoon for almost forty more years. Finally, Australian voice artist and animation historianKeith Scott discovered his name correctly in the Warner Bros. Archives.
