Throughout the ages, there is a history of attachments between two people, attachments so great that their names become immortal. Adam and Eve, Marc Anthony and Cleopatra, Abelard crying for Heloise, Romeo seranading his Juliet, and of course, Costello calling for his Abbott! Kenny Delmar opens the show, introducing the guest stars for this evening's performance - Bud Abbott and Lou Costello, before playing the first song of the show, Keep Your Sunny Side Up.
