"During the second world war, the day after Germany invaded Holland, the German mezzo-soprano Elena Gerhardt, exiled in London, sang a programme of German song with the pianist Myra Hess at the National Gallery. Gerhardt had said to Hess that "nobody will want to hear the German language", but Hess persuaded her to sing nevertheless.
As she stepped on to the platform, she received such an overwhelming ovation that it took her some time before she was able to sing.
