The very last live performance, at 2am on Monday, was Spiers and Boden in the on-site BBC studio (acts on the stages had to finish at 12.30 I think). Their caption called them Spears and Bowden, though.
Glastonbury the Festival has a population 20 times the population of Glastonbury the town. I went in 1995 (I only live 8 miles away now) and it was like a post-apocalyptic Mad Max refugee camp. Not necessarily perfect acoustics or conditions, but a great overall experience.
With something like 2000 acts in 3 days the Beeb couldn't cover everything, but there was a bit of a preponderance of noisy guitar bands on the telly. The curious can check out some of the coverage at http://www.bbc.co.uk/glastonbury/ though I don't know if the video links will work outside the UK.
I found some of the BBC Yoof presenters a bit irritating and barely competent, apart from Lauren Laverne and Phil Jupitus, who were usually witty and on top of their material. Some of the others, I guess, are more radio types not so used to being on TV, and were a bit excitable. They do rather miss the knowledgable, ironic and world-weary but now dead John Peel, who was the calm at the centre of the storm.
Iggy Pop was pretty astonishing - not that I have ever bought a record of his, but the Stooges were fabulously energetic and relentlessly solid while managing to look like they'd just broken out of jail after doing 30 years for sex crimes.
