The Delta Rhythm Boys were an American vocal group active from 1934 to 1987.
The group was formed at Langston University in Langston, Oklahoma, in 1934 by Carl Jones, Traverse Crawford, Otha Lee Gaines, and Kelsey Pharr. They moved to Dillard University in New Orleans, Louisiana, in 1936 and worked there under Frederick Hall as the Frederick Hall Quintet and the New Orleans Quintet.
They performed on radio programs such as Amos and Andy and The Joan Davis Show, and performed on Broadway in the shows Sing Out the News and Hot Mikado. The group appeared extensively in 15 films. They resettled permanently in Europe in 1956.
Lee Gaines died of cancer in Helsinki, Finland on July 15, 1987. At Gaines's funeral, Hugh Bryant collapsed while performing, and died, apparently from a heart attack.
