Since publication in 1997, MacMillan's The Galloway Mass has established itself as one of the most popular congregational mass settings in churches of various denominations around the world. With the introduction of the revised English translation in 2010 the setting could no longer be performed liturgically in Roman Catholic churches. Alan Tavener, a keen exponent of MacMillan's sacred choral works, has now adapted the work to the new translation so that its spirited and distinctive harmonies can once again inspire Catholic worship.
