Dangerous cello performance

Today just a funny picture of a brave or stupid cellist, which loves music so much, that sees no difference where and when to perform. Here I remember a story about Pau Casals which happened during the second world war when Casals had performed in a theater while outside in the town where a disaster with bombing and pain. And nobody from the public when out, and no bomb fall down onto the theater. Don't know if it is a story or reality, I have read it in the book of his memoirs.
