A hymn commonly sung to Old 100th is "Praise God, from Whom All Blessings Flow," often known simply as The Doxology, written in 1674 by Thomas Ken, a clergyman in the Church of England. This hymn was originally the final verse of a longer hymn entitled "Awake, My Soul, and With the Sun, "though it is most commonly sung by itself as a doxology. The traditional text is thus, although a modernized version is also widely used:
Praise God, from Whom all blessings flow;
Praise Him, all creatures here below;
Praise Him above, ye heavenly host;
Praise Father, Son, and Holy Ghost.
