We start this week with an O’Jays retrospective; and continue with an investigation of recent recordings from Salif Keita, the golden voice of Mali; and we conclude with a dozen versions of "Let’s Stay Together" featuring Al Green, Jimmy Smith, Aaradhna, Alex Wilson, Edwin Starr, Rev. Robert Lowe, Tina Turner, Aaron Neville with Chaka Khan, Tuck & Patti, Billy Paul, Wallace Roney and Roberta Flack. A week of wonderful vocal stylings.
