I made a big mistake in switching off just before the tribute to the victims of 7/7, with Emeli Sande singing "Abide With Me". I wouldn't have done that if I'd known that she would be singing, as she has an amazing voice and that is my favourite hymn (it's almost enough to convert me from athewism to Christianity). Fortunately I managed to track it down online, at deadspin.com - both her performance and the accompanying dancers were remarkable.

(I understand that American viewers didn't get to see her performance, as NBC cut away to an interview with someone or other.)
