Logroño kept himself busy in the late 1970s as a voice talent for radio commercials, as a comedic actor on Puerto Rican television, and as a radio host. He co-hosted a morning radio program, "Rompiendo el Día" (Daybreak) with Puerto Rican entrepreneur and musician Silverio Pérez, and served as part of the comedic team behind "Desafiando a los Genios" (Defying the Geniuses), a popular TV mock quiz show starring, among others, actor, writer and film director Jacobo Morales and Puerto Rico's premier comedic actor, José Miguel Agrelot. Two of Logroño's TV characters would surface around this time: "Agapito Flores", a rather naive country bumpkin with a speech impairment, and "Nicky El Bro", a Nuyorican hustler. A third character, "Chinito Rivera" (a flasher that said little and wore a raincoat he was eager to open at the slightest provocation) would eventually evolve into ""El Barbarazo del Amor"", one of his radio characters.
