The Delrons started out as a five-piece group in 1962 at St. Brendan’s Catholic School in Brooklyn, New York, led by lead singer Mary Aiese (born 31 December 1945). Reparata was Aiese’s confirmation name, which she had taken from one of her favorite teachers at Good Shepherd Catholic grammar school, and which Aiese says sounded more marketable than either of her given names, Mary and Katherine. The other original members included Nanette Licari, Regina Gallagher, and Anne Fitzgerald, but they were soon replaced by Sheila Reilly, Carol Drobnicki, and Cathy Romeo. When Romeo was allegedly forced out of the group, she was replaced by Marge McGuire.
The trio released their crowning glory, ‘I’m Nobody’s Baby Now’, in 1966.
