Frank Sinatra [SEP] Hoboken Four, Harry James, and Tommy Dorsey (1935–1939)
Sinatra began singing professionally as a teenager, but he learned music by ear and never learned to read music. He got his first break in 1935 when his mother persuaded a local singing group, the 3 Flashes, to let him join. Fred Tamburro, the group's baritone, stated that "Frank hung around us like we were gods or something", admitting that they only took him on board because he owned a car and could chauffeur the group around. Sinatra soon learned they were auditioning for the "Major Bowes Amateur Hour" show, and "begged" the group to let him in on the act.
