The Lay Clerks (alto, tenor and bass) sing both with the boys and the girls. In common with many other British cathedral choirs, the choir sings every day during the week and weekends (except for Wednesdays) together with a busy schedule of broadcasts, tours, recordings and concerts. There is also a mixed-voice adult choir - the Nave Choir (the longest-running cathedral voluntary choir in the country) - which is directed by the Assistant Director of Music, and sings a service of Compline regularly on Sunday evenings during term time.
