Gwendolin Sims Warren has performed with the Metropolitan Opera and the Boston Symphony and has sung in opera houses in Europe, but she's most at home singing in church. She's the daughter and granddaughter of ministers. Now she's the minister of music and choir director at the Allen AME Church in Queens, New York. She's compiled 101 best-loved Psalms, Gospel hymns and spirituals of the African American church in her new book "Ev'ry Time I Feel The Spirit." We invited her to talk about and sing some of those songs.
