Most of the Presbyterian churches in Ghana  have what we would call blended services. They have two choirs, a traditional choir like the one pictured and a contemporary praise choir called a "Singing Band." The traditional choirs are a legacy of the missionary movement and sing traditional anthems and hymns. They all wear black robes and mortar boards and process with the clergy at the beginning of the service. This is the choir from the congregation at the Kalende church, rehearsing before the service on a Sunday morning. The Singing Band wear casual clothes and lead the congregation in praise choruses and dancing.
