O God of earth & altar

Chesterton's words have been put to many different musical settings (see several above). The chords in Rise Again are to the traditional Welsh folk song "Llangofflan" which is the tune in many American hymnals (see top 2 videos above).

In England the Vaughn Williams' setting (his arrangement of the tune "King's Lynn") is usually used (see videos 3 and 4).

You can hear the tune of Llangofflan played on 8 hand bells in the final video.
