About Clerk

A lay clerk, also known as a lay vicar, song man or a vicar choral, is a professional adult singer in an Anglican cathedral and often Roman Catholic cathedral in the UK, or (occasionally) college choir in Britain and Ireland. The vicars choral were substitutes for the canons. They are not in holy orders; the term "vicar" is derived from the Latin adjective vicarius ("substituted") and in this context simply means a deputy. The majority of lay clerks are male; however, female altos are nowadays becoming increasingly common.
