The Casinos were an American doo-wop and R&B group active during the mid-1960s. Their most notable hit, "Then You Can Tell Me Goodbye," showcased their smooth vocal harmonies and lush orchestral arrangements, typical of the pop-oriented doo-wop sound of the era. The group was led by Gene Hughes, who later became a significant figure in the country music industry. Despite their relatively brief peak of popularity, The Casinos' distinctive style left a lasting imprint on the American doo-wop and R&B scene.
