With the success of "The Goon Show", Secombe developed a dual career as both a comedy actor and a singer. At the beginning of his career as an entertainer his act would end with a joke version of the duet "Sweethearts," in which he sang both the baritone and falsetto parts. Trained under Italian maestro Manlio di Veroli, he emerged as a "bel canto" tenor (characteristically, he insisted that in his case this meant "can belto") and had a long list of best-selling record albums to his credit.
