Here's another excerpt from the "King of Jazz" article by Dennis Pereyra

"The [KIng of Jazz] movie included the first Technicolor animated cartoon segment by animators Walter Lantz (later famous for Woody Woodpecker and other characters) and William Nolan. In this cartoon, Whiteman is hunting in darkest Africa when he is chased by a lion, who is soothed with the music from his violin ("Music Hath Charms", with Joe Venuti and Eddie Lang). After an elephant squirts water on a monkey in a tree, the monkey throws a cocoanut at the elephant, which hits Whiteman on the head. The bump on his head forms into a crown. As Charles Irwin then says, "And that's how Paul Whiteman was crowned the 'King of Jazz'". One of the characters making a brief appearance in the cartoon was Oswald the Lucky Rabbit, the star of the Universal cartoon studio led byLantz. Additionally a black-and-white sound cartoon featuring Oswald the Lucky Rabbit titled "My Pal Paul", that was released in 1930 by Universal, promoted the "King of Jazz" movie by including songs from the movie and the cartoon Paul Whiteman character."
