The last time I heard a Catholic Mass in Latin was at St. John the Baptist Catholic Church in Allenstown, N.H. I received my First Communion there, and later took my confirmation vows. That last Latin Mass took place in late 1964, after which an English-language liturgy was introduced to parishes in the U.S. I was 9 and had attended Latin Masses since a toddler. A few phrases have stuck with me: “Dòminus vobìscum,” and “Kyrie eleison” come to mind. The former means “The Lord be with you,” the latter, “Lord have mercy.” But that is about it.
