The Famous Davis Sisters were a Philadelphia-based gospel group founded by Ruth ("Baby Sis") Davis and featuring her sisters Thelma, Audrey and Alfreda. At a time when the gospel groups were predominantly all-male, the Davis Sisters were breaking boundaries of their own. The ladies honed their sound being raised in the Fire-Baptized Holiness Church in Philadelphia. They were signed to their first recording contract in 1947, and were making Gospel music until 1985, when they retired. Here they are singing We'll Understand It Better By And By.
In another appearance on TV Gospel Time with Brother Joe May, the ladies performed I Believe I'll Go Back Home. I managed to find the sisters credited for the composing of the song.
Have a great Sunday!
