Professor Ludwig von Drake plays a variety of popular music, all of which he wrote. First, ragtime: the Rutabaga Rag, with vegetables dancing in stop-motion. Next, the Charleston, with cut-out animation of a singer and dancers. Dixieland and more cut-out animation; the crooner/love ballad; 50's doo-wop; and finally, rockabilly.
