He tells you what he'd do. He'd throw away the cars and the bars and the wall and make sweet love to you! Singin joy to the world! All the boys and girls! Joy to the fishes in the deep blue sea! Joy to you and me!
You see him, he's a king of the world. He hung out with Jeremiah the Bullfrog, and made sweet love to you. WHILE SINGING. Yep.
