In 1957 he co-founded the "Twentieth Century Church Light Music Group" with Patrick Appleford, to "promote the use of worship music written in a style based on popular light music of the mid-twentieth century".
He became Fr. Gerard Beaumont CR when he joined the Anglican religious order, Community of the Resurrection, Mirfield.
He published "Beaumont Meets Reflection" an original LP in 1970, just before he left England for his final posting with the Community of the Resurrection in South Africa.
