His career spanned most of the 20th century and an extraordinary range of repertoire: Monteverdi (under Nadia Boulanger), Machaut, Mozart, Bach, Couperin, Dowland, Schubert, Satie and even Noel Coward. He sang at Glyndebourne 480 times, created a role for Stravinsky, made his Met debut at age 85 and his Wigmore Hall debut at 86, and performed into his 90s.
