Eavis turns down banknotes for Banksy

That giant Banksy toilethenge on the Glastonbury festival site? A mystery buyer is offering good money for that. Michael Eavis has turned them down, though:

"I'm not going to sell it but I'm going to take it down though. I don't sell other people's art. That's not what I do."

Apart from, erm, the performance art which you sell on through the Glastonbury tickets.
