Nino Valenti is Johnny Fontane’s boyhood friend and eventual musical collaborator. Like Fontane, Valenti is also one of Don Vito Corleone’s godsons. A skilled mandolin player and songwriter, Valenti sings backup for Fontane and works as a truck driver for the Corleone Family, though Don Corleone declines to give him a bigger role in the Family’s criminal rackets. After Johnny makes it big in Hollywood, he promises to get Nino a job in California but reneges on this promise. Nino first appears in the novel as he plays mandolin at Connie Corleone’s wedding. Later, he reconnects with Johnny, who records several new records with Nino, introduces him to lascivious Hollywood starlets, and even gets him some film roles that make him a minor movie star. Despite his success, however, Nino is an alcoholic who ignores Jules Segal’s warnings and eventually drinks himself to death at a young age.
