Since the days of King Canute (c. 1000) music has played an important role in the on-going life of the Cathedral. The Cathedral has 4 choirs directed by musicians of great distinction: Boy Choristers; Girl Choristers; The Ely Imps; Ely Cathedral Octagon Singers ... Concerts, performed by one, some or all of its choirs are a regular feature and its choir(s) are sometimes joined by famous conductors, singers or orchestras ... The Cathedral Organ is regarded as one of the largest and finest instruments of its kind in the South East of England. Organ recitals are a regular feature in the Cathedral diary.'
