is in joint memory of Michael and Edward Elgar and the unfinished Cello Concerto, on which Howells had been working at the time of the boy's death and which he found himself unable to complete. A Sequence for St Michael and the motet Take Him, Earth, for Cherishing have also been associated with Howells's grief for Michael, as have two of Howells's hymn tunes, the best-known of which is his tune for the hymn "All My Hope on God is Founded" by Robert Bridges ("A Hymn Tune for Charterhouse"), which was renamed Michael for its publication in The Clarendon Hymn Book in 1936. Howells also wrote the tune Twigworth (1968) for the hymn "God is love, let heaven adore him". To a greater or lesser extent, however, much of Howells' subsequent music shows the influence of this loss. From the late 1930s, Howells turned increasingly to choral and organ music, composing a second series of Psalm Preludes followed by a set of Six Pieces (begun 1939), of which the third, Master Tallis's Testament, a particular favourite of the composer's, recalled his formative experience of Vaughan Williams' Tallis Fantasia. A set of Four Anthems, originally titled In Time of War and including the popular O Pray for the Peace of Jerusalem and Like as the Hart, followed in early 1941. In August of that year, Howells was invited to serve as acting organist of St John's College, Cambridge, replacing Robin Orr who was away on active service in World War II. Howells' association with Cambridge, which lasted until the end of the war in 1945, was a productive and happy period for him, and led directly to the works for which he is most remembered. He later recalled being challenged by the Dean of King's College, Eric Milner-White, to write a set of canticles for the choir. The result was the Te Deum and Jubilate of the service known as Collegium Regale, performed in 1944, followed the next year by the Magnificat and Nunc Dimittis, and completed in 1956 by the Office of Holy Communion. Collegium Regale, the Gloucester Service (for Gloucester Cathedral, 1946) and the St Paul's Service (for St Paul's Cathedral, 1951) remain the best known and most admired of the many settings of the Anglican liturgy written by Howells for particular choirs and buildings over the next thirty years.
