Come Sunday morning, Mr. Gates plays piano and serves as music director at four different churches around Clarksdale. Some of the churches have a choir, others just a congregation. Either way, Mr. Gates leads everyone in songs he knows by heart. A few favorites: “He Keeps On Blessing Me,” “I’ll Let Nothing Separate Me from My Love of God,” “I Am So Grateful,” “Lord I Know You Been So Good,” “I Owe Him Me,” and “I Found Something.”
