The music of the Welsh composer William Mathias (1945-1992) was represented in the second volume of Hyperion's series The English Anthem with As truly as God is our Father, a work which was specially written for a Royal visit to St Paul's Cathedral. Mathias wrote an anthem for another Royal occasion, the marriage of HRH The Prince of Wales and Lady Diana Spencer, which took place in St Paul's Cathedral on 29 July 1981; Let the people praise thee, O God, Op 87, is a setting of the Deus misereatur, Psalm 67.
