The Choir of Westminster Abbey is renowned worldwide as one of the finest choirs of its type. Comprising some thirty boy choristers (all of whom are pupils the Abbey’s unique Choir School) and twelve professional adult singers (known as Lay Vicars), the Choir plays a central role both in the daily choral services in the Abbey and in the many royal, state and national occasions which take place there. Notable recent events have included services to mark the Centenary of the Battle of the Somme and to celebrate the life and work of Sir Terry Wogan, both of which were broadcast nationally, and the Wedding of Their Royal Highnesses The Duke and Duchess of Cambridge in April 2011, which was seen by a worldwide television audience of over two billion people.
