As a composer he has received many commissions in recent times, and 1993 saw the premiere of his opera St. Francis at Eton College. He has written instrumental and chamber music and many choral works including the anthem Let us invoke Christ. The composer has kindly provided the following note:
A commission to write for St Paul's was a most welcome challenge, not only because of my long-standing admiration for John Scott and his work with the choir, but also because of the extraordinary acoustics of the cathedral. I wished to come up with a work which would be enhanced by the reverberations swirling around the dome and the length of the nave, and it also needed to have an air of celebration befitting its first performance during the opening service of the 1993 City of London Festival. By a happy coincidence I found an inspiring ancient eucharistic text which I hope has evoked just this mood, and the musical setting of which will, I hope, sound glorious in the unique sound-world of St Paul's.
