Apart from his work as a singer, he was also a television host, as well as technical and musical director, and prolific songwriter. He wrote songs for many of his contemporaries. Many of these became hits in Puerto Rico, and occasionally in the rest of Latin America. One of his self-penned songs was "El Negro Bembón", a hit for Cortijo y su Combo in the mid-1950s. The song, with local circumstances and character name changed, became "El Gitano Antón", a huge hit for Catalan rumba singer Peret in Spain around the mid-1960s. Bobby Capó wrote the score and songs for the movie "MARUJA" that was filmed at the end of the 1950s in Puerto Rico.
