Cab Calloway was a master of energetic scat singing and led one of the United States' most popular African-American big bands from the start of the 1930s through the late 1940s. In 1931, he recorded his most famous song, "Minnie the Moocher". That song, along with "St. James Infirmary Blues" and "The Old Man Of The Mountain," was performed for the Betty Boop animated shorts Minnie the Moocher, Snow White and The Old Man of the Mountain, respectively. Through rotoscoping, Calloway not only gave his voice to these cartoons, but his dance steps as well.
