 The instrumentals were originally recorded by Prima—who also played the trumpet—and his band, Sam Butera & The Witnesses, but the music was replaced by one written by the film's composer, George Bruns, and orchestrated by Walter Sheets.The "scat dialogue" between Baloo and King Louie was the result of two recording sessions.Louis Prima recorded first, with the intent that Baloo—played in his recording by Butera—would simply repeat what Louie scatted, but Phil Harris decided not to imitate Prima's recording and made up his own.
