The governors hold proprietorial responsibility, and some are representatives of the Universities of Oxford, Cambridge and London.

The school has had several distinguished directors of music, most notably Gustav Holst (1905–34) and Herbert Howells (1936–62).

Holst composed his St Paul's and Brook Green suites for the pupils at the school.

John Linton Gardner held a part-time position as director of music at the school.

Gardner wrote many memorable pieces for the school, including his popular Christmas carols Tomorrow Shall Be My Dancing Day and The Holly and the Ivy.
