Leonard Caston

Leonard "Baby Doo" Caston (June 2, 1917 – August 22, 1987) was an American blues pianist and guitarist. He is best noted for the tracks "Blues at Midnight" and "I'm Gonna Walk Your Log". In 1940, Caston recorded his first solo record for Decca, "The Death of Walter Barnes", with Robert Nighthawk on harmonica.

The Five Breezes disbanded in 1941, and Caston began playing in the Rhythm Rascals Trio with Alfred Elkins and Ollie Crawford. The group did USO tours and in 1945 performed at a conference for Dwight Eisenhower, Bernard Montgomery, and Georgy Zhukov. After the war, Caston recorded under his own name and with Roosevelt Sykes and Walter Davis and performed in many studio sessions. He also recorded again with Dixon as the Four Jumps of Jive and the Big Three Trio, playing in both groups with Bernardo Dennis. Ollie Crawford joined this group soon after Dennis's departure. The Big Three Trio recorded for Columbia Records and Okeh Records.

The Big Three Trio's last sides were recorded in 1952, but the group did not officially break up until 1956. Caston continued performing for decades afterwards, reuniting with Dixon to perform in 1984.

Caston released an album, Baby Doo's House Party, shortly before his death from heart disease in Minneapolis, Minnesota, in 1987.

His son, Leonard Caston, Jr., is an R&B singer and songwriter, who sang with the Radiants, and wrote songs for Motown Records, among other endeavors.
