Born in Naples, Italy as the son of poet Ernesto Murolo and Lia Cavalli, Murolo showed a passion for music at a young age and began singing and playing the guitar as a child.
Murolo won the Italian high diving championship in 1937, and attributed his remarkable lung capacity to the long practice of water sports.
In addition to establishing himself as a concert artist and a popular figure on radio, with a romantic, sentimental sound, he also did some acting in movies, appearing in the 1953 crime drama The Counterfeiters, made in Italy by director Franco Rossi.
Antologia cronologica della canzone partenopea and released between 1963 and 1965, is an annotated compendium of Neapolitan song dating back to the 12th century.
