[r] Mavis Staples is one of the greatest singers of our time -- a gospel, soul, and R&B vocalist known for her deep, rich voice. She began as the lead singer of The Staple Singers, a family gospel group formed by Pops Staples and several of his children. The Staple Singers achieved several hits with "Respect Yourself", "I'll Take You There" and "Let's Do It Again". They also became a musical voice of the American civil rights movement with their protest music. Jesse will ask about how Staples balanced her gospel roots with a career in popular music and about what is was like working with Curtis Mayfield and - yes - Prince. Plus, the McElroy brothers from My Brother, My Brother and Me join us to answer listeners’ pop culture questions.
