It is certainly true Fr. Leo F. McNamara never said the new mass, although he didn't continue to say the Traditional Latin Mass with the approval of his superiors. After leading the Faithful at St. Adrian's for more than 35 years, Fr. Mac was involuntarily "retired" by Cardinal Cody in 1966. After that time, he was relegated to the left side altar, where he continued to offer Mass until his death. The Faithful filled the left side of the church for Mass, while the few people who came for the N.O. mess, (complete with guitars and banjos) had a service with Fr. John Jordan at the main altar.
I wonder what has become of St. Adrian's now.
