I’m not 100% crazy about Richard Strauss’ music, except for “Death and Transfiguration”, which I love. But I can never listen to it now without remembering the remark about Strauss attributed to Hans Knappertsbusch: “I knew him very well. We played cards every week for 40 years. And he was a pig.”
There’s obviously something to know, there, but I prefer not knowing it.
