A powerful singing voice has joined the heavenly chorus, praising God in eternity. James Houston (Dickie) Hillis, Sr., sang a commanding bass in the popular and widely traveled Harmony Echoes Quartet for 42 years. He was also a stalwart in the lower registers in singing at his home church, Rockliff Church of Christ. Throughout his life he struggled with a speech impediment, but his singing was impressively rich, strong and assured. He died Saturday, Sept. 2, after an extended illness.
