This Book is Dedicated to our children:
Charles and Sarah,
Shaolu, Jason and Sam,
Alfred
As I walked down by the river
Down by the frozen fen
I saw the grey cathedral
With the eyes of a child of ten.
O the railway arch is smoky
As the Flying Scot goes by
And but for the Education Act
Go Jumper Cross and I.
Ballad for Katherine of Aragon, Charles Causley (1947)
Choral Symphony No.3, Gala and Gloria, Will Todd (2004)
First performed Durham Cathedral,
Riverside Band and banner marching its length,
closing with Cathedral bells
