I saw soprano Jane Manning, who died on 31st March aged 82, perform onstage just once. It was 1976 and my first ever visit to the Wexford opera festival. She sang the difficult, narrator role of Governess in Benjamin Britten’s The Turn of the Screw. Her interpretation revealed the precise musical weapon of a soprano voice, all buttoned-up in a Miss Prim persona. Manning was disturbing in her intensity.
