Tympany Five was a successful and influential rhythm and blues and jazz dance band founded by Louis Jordan in 1938. The group was composed of a horn section of three to five different pieces and also drums, double bass, guitar and piano. 　　Louis Jordan and His Tympany Five created many of the most influential songs of the early R&B and Rock n' Roll era, including Let The Good Times Roll, Keep A-Knockin', and Caldonia. Carl Hogan's opening riff to Ain't That Just Like A Woman later became one of rock's most recognizable riffs in Chuck Berry's Johnny B. Goode. 　　Jordan first formed the band as "The Elks Rendezvous Band", named after the Elks Rendezvous jazz joint in Harlem. The original lineup of the sextet was Jordan (saxes, vocals), Courtney Williams (trumpet), Lem Johnson (tenor sax), Clarence Johnson (piano), Charlie Drayton (bass) and Walter Martin (drums). The various lineups of the Tympany Five (which often featured two or three extra players) included Bill Jennings and Carl Hogan on guitar, renowned pianist-arrangers Wild Bill Davis and Bill Doggett, "Shadow" Wilson and Chris Columbus on drums and Dallas Bartley on bass. Jordan played alto, tenor and baritone saxophone and sang the lead vocal on most numbers. The band found fame after opening for The Mills Brothers at the Capitol Lounge in Chicago in 1941. 　　In 1941, they were transferred from Decca's "race" label to its Sepia Series, featuring artists thought to have the crossover potential to appeal to both black and white audiences. Jordan was always proud of the fact that the Tympany Five's music was just as popular with white as it was with black people.
