There are such things (1942)

'In 1940, Tommy Dorsey lured Sinatra away from (Harry)James and launched him on the road to stardom. The Dorsey years (1940-42) are often hailed as seminal in Sinatra's development, but Yank Lawson, who watched young Frank from the trumpet section, disagreed. "I don't think Sinatra learned much with Dorsey," Yank told me in 1992. "His talent was already developed when he got there. He became so famous during those years because Dorsey had a good publicity machine, knew how to package him and had the money to do it right." Sinatra himself disagreed. In a famous interview with Arlene Francis in 1977, Sinatra credits Dorsey with teaching him how and when to breathe for maximum effect'. (www.pitt.edu).
