For an apparent folksong, On Ilkley Moor baht ‘at has a very reliable provenance. The tune, Cranbrook, was devised in 1805 by Thomas Clark, a shoemaker of Canterbury and prolific composer of hymns for, in particular, Nonconformist churches of southeastern England. It was sung to When Shepherds Watched Their Flocks By Night.Some decades later, an East Riding church choir on an outing is said to have created the new words following an incident on their walk. In the many years that the song has been sung as On Ilkley Moor, ever more rambunctious interpolations have been added, e.g. ‘yum, yum, yum’ or ‘up the ducks!’ following ‘Then we will go and eat up ducks’.In this version by composer and Curwen & Sons Chairman Maurice Jacobson, a descant has been added at verses 3, 6 and 9, and a lively interplay arranged between high and low Voices in the verse and Chorus.
