When the post-Vatican II liturgical reform was getting underway in 1966, and again when the reformed Mass had been unveiled in 1971, petitions signed by intellectuals and cultural figures – poets, writers, artists, musicians – called for the preservation of the older liturgy, alongside the new. These voices were heard by Pope Paul VI, who tried to insist on the preservation of the sung Latin Office in Sacrificium laudis in 1966, and granted England and Wales permission for continuing celebrations of the older Mass in 1971. This was extended to the whole world by Pope John Paul II in 1984.
