Say Amen, Somebody (1982)

Gospel music is the subject of this lively film, which explores the history of the faith-rooted musical style. While the documentary features a number of gospel musicians, it spends the most time looking into the considerable contributions of Thomas A. Dorsey, a pioneering songwriter and pianist, and his popular associate, singer "Mother" Willie Mae Ford Smith. Also included are numerous concert performances by the Barrett Sisters, Sallie Martin and other gospel luminaries.
