Illustrated talk by Erik Routley, Chaplain and Tutor in Church History at Mansfield College, Oxford.
Maurice Frost's recently published book English and Scottish Psalm and Hymn Tunes makes available a great deal of church music either little known or long forgotten, including the original versions of many of our hymns and metrical psalms as well as much of the music published for congregational use between the Reformation and the reign of Charles II. Dr. Routley discusses the music and its historical significance. The title of his talk is taken from Queen Elizabeth I's 'Injunction to the Clergy' (1559) in which the use of hymns is authorised for the Church of England.
The illustrations are sung by the Trinity Singers (conductor, W.C. Anscombe), with unison illustrations by an amateur group.
