Franchi became a headliner in Las Vegas, and starred in concerts and cabarets on several continents. His earliest ambitions and studies had been directed toward an operatic career, but he instead found his niche in popular and romantic music. Franchi performed musical comedies on stage, appeared on numerous television variety shows, and starred in a major motion picture. He became an American citizen in 1972. After gaining success, Franchi was a benefactor and philanthropist, donating his time and talent to many causes. For his longtime support of Boys' and Girls' Towns of Italy, he was posthumously awarded the title of cavaliere in the Order of Merit (Stella al merito del lavoro) by the Italian Government.
