'Christ Is Our Guiding Light' was composed by Eric H. F. Law and works well as a round or canon. There's also a lovely descant line for a cantor to sing.
Sheet music can be found in Singing In Community, our latest songbook published by Augsburg Fortress.
Here's an audio recording of Emily Scott teaching this song and giving some helpful suggestions for how to lead it paperlessly.
Here's a video of Ruth Williamson leading Christ is Our Guiding Light at Music that Makes Community in Los Angeles in October of 2008.
