It sounds like a fairly small scale local festival (10,000) as opposed to a huge rock event, but I met someone a few weeks ago who'd been to a previous Bestival and she said she'd enjoyed it very much, spaced-out though she was at the time.
The downer for me would be Chuck Berry. I saw him a few years ago and it rated as probably the worst gig I've ever been to in terms of a performer treating his audience with complete contempt. At the time I imagined I'd be seeing a glimpse of something legendary, not knowing how much his act had deteriorated. He'd begun using cheap pick-up bands, particularly when touring abroad, and would only play for 40 minutes or so, just going through the motions, before taking the money and running. I wouldn't even cross the road to see him again. I can't understand how someone who's occupied such a seminal position in the history of rock and roll has allowed himself to sink to such depths. The man's an absolute disgrace.
The upside would be Billy Bragg, who I didn't really care for in his early years but who has gradually grown in stature and is better now every time I see him. I saw him last year in his own show at the Dome Brighton and again a few weeks ago, at the same venue, where he was part of the Imagined Village, a show taking a look at multicultural Britain (where Billy's slant was on the concept of Englishness) combining the talents of UK folkies like Martin Carthy, his daughter Eliza, and Chris Wood, along with other musicians playing the cello, sitar, bhangra drums and synthesisers from bands like the Afro Celt Sound System and Transglobal Underground. Billy Bragg and Sheila Chandra contributed vocals and the British 'dub poet' Benjamin Zephaniah provided an updated electro-reggae version of the traditional ballad 'Tam Lyn'. It might not all have worked, but at least they were attempting something new and vital.

U.S. towies with leftward leanings might know of Billy Bragg's versions of unrecorded Woody Guthrie songs, put out in the Mermaid Avenue albums:
