"Rock of Ages" is a popular Christian hymn by the Reverend Augustus Montague Toplady written in 1763 and first published in The Gospel Magazine in 1775.
"Rock of Ages" is usually sung to the hymn tune "Toplady" by Thomas Hastings or "Redhead 76" by Richard Redhead or "New City Fellowship" by James Ward. "Toplady" is most typical in the United States and "Redhead 76" in the United Kingdom, although both tunes circulate in the churches of both countries.
