Mr. Wolcott was born in Flint, Mich. In 1927, he joined the Jean Goldkette band, playing piano and scoring music for Tommy and Jimmy Dorsey. He became an arranger for Paul Whiteman, Benny Goodman and the Dorsey brothers. Mr. Wolcott also arranged music for radio stars Rudy Vallee, George Burns and Gracie Allen.
He joined Walt Disney in 1934 and during his 10 years there wrote songs for or arranged film scores of ''The Reluctant Dragon,'' ''Bambi,'' ''Saludos Amigos,'' ''The Three Caballeros,'' ''Song of the South,'' ''Make Mine Music!'' and ''Fun and Fancy Free.''
He went to Metro-Goldwyn-Mayer in 1950 and is credited with bringing rock-and-roll to the motion picture screen, prevailing on the producer of the film ''The Blackboard Jungle'' to incorporate Bill Haley's recording of ''Rock Around the Clock'' into the film. Mr. Walcott also scored that 1955 movie.
