Ryan’s parish do this hymn with a text by George William Kitchin, revised by Michael Robert Newbolt and set to CRUCIFER by Sydney Hugo Nicholson.
Text and music are at Hymnary, although my copy in Together in Song has slightly different lyrics eg “Come, people” vs “Come, brethren” vs “Come, Christians”.
This song is all over You Tube.
