"One O'Clock Jump" is a jazz standard, a 12-bar blues instrumental, written in 1937 by Count Basie, with arrangement from Eddie Durham and Buster Smith.[citation needed] The original recording of the tune by Basie and his band is noted for the saxophone work of Herschel Evans and Lester Young; trumpeting by Buck Clayton, Walter Page on bass, and Basie himself on piano. "One O'Clock Jump" was the theme song of the Count Basie Orchestra; they used it to close each of their concerts for the next half century. It was reportedly titled "Blue Ball" at first, but a radio announcer feared that title was too risqué. It was listed in the Songs of the Century.
