No matter. She had long planned to retire from singing at age 50, in part because of family concerns. She and her husband, journalist Peter Greenough, whom she married in 1956, had two children - Meredith (Muffy), who is deaf, and Peter Jr. (Bucky), who is mentally disabled. Greenough died last year.
The fact that she didn't have to worry about supporting her family - Greenough was independently wealthy - meant that she could choose her projects with a freedom even the greatest stars don't enjoy. She bridled at repertoire-style opera in which her characterizations were inevitably compromised by productions created for other singers. Those productions didn't allow her to convey the myriad effects she envisioned.
