My pal paul (1930)

Oswald the Rabbit puts on a concert for a group of barn animals - but when they discover that he's miming to a record of his idol, Paul Whiteman - they boo and shun him. Oswald wanders off in shame to hang himself from the nearest tree and is stopped by none other than Whiteman himself who happens along in his car. The two begin performing music using parts of the car which leads to some highly surrealistic setpieces (dancing tools - a hood ornament that does an Indian dance, etc.) This rare and whimsical cartoon was used to promote THE KING OF JAZZ and makes reference to same.
