The St Patrick's Service was written in the spring of 2017 for a "Come and Sing" Evensong in Armagh Cathedral, one of a number of events organised to celebrate St Patrick's Day in Ireland's ecclesiastical capital. The aim was to enthuse parish choirs to sing Choral Evensong again, and to provide them with music which they could take back to their parishes. Both vocal and organ parts are written with this in mind, thus the limited vocal range and an accompaniment which can be play on an instrument of one manual, with or without pedals.
