Light-Up Time (1949–50)
Media critic John Crosby called the teaming of Sinatra and opera singer Dorothy Kirsten “what seems at first, or even second, blush to be the most unlikely combinations of singers on the air.” The two singers co-starred in Sinatra’s Light-Up Time, the title of which came from an advertising slogan for sponsor Lucky Strike cigarettes. The slogan: “Light up a Lucky—it’s light-up time.” Jeff Alexander led the orchestra, and Don Wilson was the announcer. The program debuted September 5, 1949 and ended June 2, 1950. In March 1950, film commitments prevented Alexander from continuing on the program, and Skitch Henderson became the program’s orchestra leader.
