Free jazz
Free jazz and the influence of world musicians on the medium pushed jazz singing nearer to avant-garde art music. In the 1960s Ward Swingle was the product of an unusually liberal musical education. He took the scat singing idea and applied it to the works of Bach, creating The Swingle Singers. Scat singing was also used by Louis Prima and others in the song "I Wan'na Be Like You" in Disney's "The Jungle Book" (1967).
