In 1939, Frank Sinatra scored his very first success, "All Or Nothing At All," with trumpeter Harry James' Orchestra. The following year the young singer began an extraordinary two year apprenticeship with the much classier Tommy Dorsey Orchestra, a regimen which taught him everything he needed to know about musical taste and judgement if not popular adulation. Make no mistake, however; from the beginning, through sheer dint of will, Sinatra managed to make his time with the master trombonist and bandleader a collaboration of musical equals.
