Msgr. Robert Brennan was assigned to Long Beach, New York as pastor of Our Lady of the Isle Parish. He served as an associate pastor at St. Agnes for 16 years. Msgr. Brennan will continue to be the Vicar General for the Diocese of Rockville Centre. In August of 2020, Bishop John O. Barres appointed the Rev. Michael F. Duffy as the new Rector of St. Agnes Cathedral. At 35, he is the youngest rector in the history of St. Agnes Cathedral. Organ and music For 19 years, St. Agnes Cathedral did not have a major pipe organ in the cathedral proper. The original pipe organ from the 1930s was built by the Wurlitzer Company and remained in use until 1972. The rector of that time (Monsignor Edward Melton) was concerned with maintaining the parish schools so an electronic organ was temporarily installed. A small Moeller pipe organ was located in the 1960s and 70s near the Blessed Sacrament Chapel and later moved to the Lower Church. The previous church building of 1905 contained a Midmer pipe organ which was enlarged by a Rockville Centre pipe organ builder when a larger rear gallery was built in the "Marble Church." To mark the Jubilee Year of 2000 plans were made to build a new pipe organ for St. Agnes Cathedral Parish. The organ is located in 3 locations in the cathedral to serve the congregation, choirs, and other ministers. In 2001, The Wicks Organ Company of Highland, Illinois, installed the organ. St. Agnes Cathedral has three choirs: The Cathedral Choir of Men and Boys (founded in 1957), the Junior and Senior Divisions of the Cathedral Girls Choir, and the Cathedral Chorale and Schola Cantorum. The choirs are directed by Mr. Michael L. Bower. On May 1, 2019, St. Michael's Choir School visited St. Agnes Cathedral as part of their 2019 New York Tour. They collaborated with the Cathedral and Diocesan Choirs of the Diocese of Rockville Centre as part of the concert.
