The war, as is recorded by Percy Scholes in The Mirror of Music, had damaged orchestral music, but the Promenade Concerts survived. Composers not on active service, and those, the majority, who were, continued at work, however hampered. The Bechstein Hall, of which Neville Lytton had wittily deplored in pre-war years the ‘spaghetti frieze’, wondering when music-lovers would appreciate line proportion as they did musical proportion, and which had been closed because enemy property, re-opened as the Wigmore Hall. Jelly’s first concert after the war, in January 1919, was only a continuation of her work in schools. She went to St Leonard’s School in St Andrews. She had just recovered from ‘Spanish ’Flu’, a severe attack of that grave epidemic in which many died. She was told that violent nose-bleeding had saved her life.
