Thomas Francis Dorsey was born on November 19, 1905 was an American jazz trombonist, trumpeter, composer, and bandleader of the Big Band era. He was known as "The Sentimental Gentleman of Swing". He was the younger brother of bandleader Jimmy Dorsey." Dorsey disliked improvisation and had a reputation for being a perfectionist. He was volatile and also known to hire and fire (and sometimes rehire) musicians based on his mood.
By 1939, Dorsey was conscious of criticism that his band lacked a jazz feeling and Dorsey hired arranger Sy Oliver, from the Jimmy Lunceford band to arrange for his band. Sy Oliver's arrangements for Tommy Dorsey include "Well Git It" and "On The Sunny Side of the Street".
In 1940, Dorsey hired singer Frank Sinatra from bandleader Harry James. Frank Sinatra made eighty recordings from 1940 to 1942 with the Dorsey band. Two of those eighty songs are "In The Blue of Evening" and "This Love of Mine". Frank Sinatra achieved his first great success as a vocalist in the Dorsey band and claimed he learned breath control from watching Dorsey play trombone.
In turn Dorsey said his trombone style was heavily influenced by that of Jack Teagarden. Among Dorsey's staff of arrangers was Axel Stordahl who arranged for Frank Sinatra in his RCA, Columbia and Capitol years. Another member of the Dorsey band was trombonist Nelson Riddle, who later had a partnership as one of Sinatra's arrangers and conductors in the 1950s and afterwards.  Another noted Dorsey arranger, who in the nineteen-fifties, married and was professionally associated with Dorsey veteran Jo Stafford, was Paul Weston Bill Finegan, an arranger who left Glenn Miller's civilian band, arranged for the Tommy Dorsey band from 1942 to 1950.
