Doc Cook and his 14 Doctors of Syncopation worked at the Casino dance hall at the White City amusement park during the late 1920s. The amusement park was located at 63rd and South Parkway in Chicago. Cook's band also toured the midwestern states. The group broke up after having all their instruments stolen from the bandstand during a break at a marathon dance contest.

Freddie Keppard (born February 27, 1890, New Orleans, Louisiana, USA - died July 15, 1933, Chicago, Illinois, USA) was an American jazz cornetist, trumpeter and bandleader.

He is regarded as the first worthy successor to the great cornetist Buddy Bolden. His first professional engagement was with nell'Olympia Orchestra (around 1905) and then he played with Frankie Dusen's Eagle Band. In 1914, he moved to Los Angeles, California with the Original Creole Orchestra and toured the United States. About 1917, he moved to Chicago and worked with Doc Cook, Erskine Tate, Ollie Powers and Charlie Elgar. Keppard recorded between 1923-1927 with the Jazz Cardinals. Keppard suffered from alcoholism and tuberculosis in his final years and his playing suffered as a result. Brother of jazz guitarist and tubist Louis Keppard.
