Tom Colvin (b. 1925; d. 2000) was trained as an engineer and worked in that profession in Burma and Singa­pore from 1945 to 1948. After studying theology at Trinity College, Glasgow University, he was ordained in the Church of Scotland in 1954. He served as missionary in Nyasa­land (now Malawi) from 1954 to 1958, in Ghana from 1958 to 1964, and again in Nyasa­land from 1964 to 1974. His work there included preaching, education, and community development. After completing his missionary work, Colvin became a minister in the United Reformed Church of England and served an inner-city church in London. He returned to Africa in 1984 as a development consultant to the Zimbabwe Christian Council. He is now retired in Edinburgh. Colvin's writings include Christ's Work in Free Africa (1964) and three collections of hymns, many written in collaboration with African Christians–Free to Serve (1966), Leap My Soul (1976), and Fill Us with Your Love (1983).

John Bell (b. 1949) was born in the Scottish town of Kilmarnock in Ayrshire, intending to be a music teacher when he felt the call to the ministry. But in frustration with his classes, he did volunteer work in a deprived neighborhood in London for a time and also served for two years as an associate pastor at the English Reformed Church in Amsterdam. After graduating he worked for five years as a youth pastor for the Church of Scotland, serving a large region that included about 500 churches. He then took a similar position with the Iona Community, and with his colleague Graham Maule, began to broaden the youth ministry to focus on renewal of the church’s worship. His approach soon turned to composing songs within the identifiable traditions of hymnody that found began to address concerns missing from the current Scottish hymnal:

 

I discovered that seldom did our hymns represent the plight of poor people to God. There was nothing that dealt with unemployment, nothing that dealt with living in a multicultural society and feeling disenfranchised. There was nothing about child abuse…, that reflected concern for the developing world, nothing that helped see ourselves as brothers and sisters to those who are suffering from poverty or persecution. [from an interview in Reformed Worship (March 1993)]

 

That concern not only led to writing many songs, but increasingly to introducing them internationally in many conferences, while also gathering songs from around the world. He was convener for the fourth edition of the Church of Scotland’s Church Hymnary (2005), a very different collection from the previous 1973 edition. His books, The Singing Thing and The Singing Thing Too, as well as the many collections of songs and worship resources produced by John Bell—some together with other members of the Iona Community’s “Wild Goose Resource Group,” are available in North America from GIA Publications.
