Melba had a strong supporter in London, Lady de Grey, whose views carried weight at Covent Garden. Melba was persuaded to return, and Harris cast her in "Roméo et Juliette" (June 1889) co-starring with Jean de Reszke. She later recalled, "I date my success in London quite distinctly from the great night of 15 June 1889." After this, she returned to Paris as Ophélie, Lucia in "Lucia di Lammermoor", Gilda in "Rigoletto", Marguerite in "Faust", and Juliette. In French operas her pronunciation was poor, but the composer Delibes said that he did not care whether she sang in French, Italian, German, English or Chinese, as long as she sang.
