I saw an advert for this yesterday, and of course was instantly stunned. On sunday evening, the beeb will air a program in which David Attenborough meets Barack Obama. It promises to be an incredible piece of television; the two great men are said to discuss the natural world, climate change and so on. I suppose it’s quite a coup for the bbc, although it was apparently Obama who requested the meeting. Something to look forward to, then – expect my customary rave on here on Monday morning.
