Tommy and Jimmy Dorsey first teamed up together on records as the Dorsey Brothers in 1928 but the groups they led through 1933 were strictly studio affairs, featuring classic jazz and hot dance music along with some ballads. In 1934, they decided to put together a regular orchestra and by 1935, with Bob Crosby (and later Bob Eberle) taking the vocals and Glenn Miller providing many of the arrangements, the group was on the brink of success in the early swing era. However, a well-publicized argument at a ballroom over the tempo of "I'll Never Say Never Again Again" led to Tommy Dorsey immediately leaving and starting his own separate orchestra.
Thomas Francis "Tommy" Dorsey, Jr. (November 19, 1905 - November 26, 1956) was an American jazz trombonist, trumpeter, composer, and bandleader of the Big Band era. He was known as "The Sentimental Gentleman of Swing", because of his smooth-toned trombone playing. Although he was not known for being a notable soloist, his technical skill on the trombone gave him renown amongst other musicians. He was the younger brother of bandleader Jimmy Dorsey. After Dorsey broke with his brother in the mid-1930s, he led an extremely popular and highly successful band from the late 1930s into the 1950s.
James "Jimmy" Dorsey (February 29, 1904 – June 12, 1957) was a prominent American jazz clarinetist, saxophonist, trumpeter, composer, and big band leader. He was known as "JD". He composed the jazz and pop standards "I'm Glad There Is You (In This World of Ordinary People)" and "It's The Dreamer In Me".
Alton Glenn Miller (March 1, 1904 – missing in action December 15, 1944) was an American big band musician, arranger, composer, and bandleader in the swing era. He was the best-selling recording artist from 1939 to 1943, leading one of the best known big bands. Miller's notable recordings include "In the Mood", "Moonlight Serenade", "Pennsylvania 6-5000", "Chattanooga Choo Choo", "A String of Pearls", "At Last", "(I've Got a Gal In) Kalamazoo", "American Patrol", "Tuxedo Junction", and "Little Brown Jug". While he was traveling to entertain U.S. troops in France during World War II, Glenn Miller's aircraft disappeared in bad weather over the English Channel.
Dorsey Brothers Orchestra began recording in 1928, but didn't become a real band until 1934. The 1934 band featured both Glenn Miller and Bob Crosby, but didn't last long because Tommy and Jimmy were always fighting with each other and in 1935 Tommy stormed off the stage quitting the orchestra. He soon took over Joe Haymes Orchestra re-naming it the Tommy Dorsey Orchestra. Jimmy continued on with the Dorsey Brothers group re-naming it the Jimmy Dorsey Orchestra. Tommy's orchestra was the more successful of the two but both bands were very successful. In 1953, Jimmy and Tommy reunited and continued playing together until Tommy's death in 1956. The Dorsey brothers had a popular television variety show on CBS in 1954 and one episode featured the first TV appearance by the then unknown Elvis Presley.
