Daniel Barenboim received an honorary KCBE in Berlin last night from the British ambassador, acting as the Queen’s representative.
The honour recognises his peace efforts in the Middle East and his lifelong association with music in London. Since he is not a British citizen, he cannot use the title ‘Sir’ and there will be no royal command: ’arise, Sir Daniel’.
Here’s more. And here’s a picture of the event from Flickr. Scrolling down, you’ll find among the guests at the dinner a suntanned Sir Simon Rattle. He’s allowed to use the Sir.
