For a pro singer in that era, his voice isn't amazing, so it's schmeared with tape doubling & room verb, but he had the absolute best arrangements. Ass shakers abound - "Lollipop" is incredible, & it's no wonder Daft Punk lifted "Cola Bottle Baby" when Sony gave them carte blanche to the corporate back catalogue.
