CLARKSVILLE, Mo. — No could tell that Tricia Luke, left, and Hanna Blackmore hadn’t performed a show together in three years – until they made the announcement. It made no difference, as the duo was well-received as one of the opening acts for the Cornet Chop Suey concert sponsored by Raintree Arts Council on Sept. 24 in Clarksville. They performed such hits as “Take Me Home, Country Roads,” “House of the Rising Sun” and a medley that included “Ring of Fire,” “Hallelujah,” “Hotel California” and “Dust in the Wind.”
