Great Sacred Music, a free lunchtime event of spoken word and music for choirs and congregations, is a regular feature of the life at witness of St Martin-in-the-Fields. Each week, a themed programme is offered which combines music with stories of how the pieces came to be written and some reflections on the theme. As well as a celebration of music, it has proved to be instrumental in the mission of St Martin's, attracting many people to the church.
