***Señor Delgado puts together an American-style variety show and takes it to Mexico City. All the Buells and Hubbards perform as a singing group, Arnaz Jr. (as Tommy the delivery boy) is invited to play drums. In his audition for the show, Jr. performs "Babalu" with a conga but absolutely CANNOT sing! His dad (as Delgado) says he's never heard of the song.
