Think people might have a misconception over some of these DJs. Two weekends back, straight from Cochella, I saw Dixon in Kampala, Uganda where he played to maybe 100 of us in a small bar at 4quid entry. He has played in Kenya the night before. Perhaps he's giving back to the people this summer, but I very much doubt Glastonbury have broken the bank to get him there. More likely he is quite looking forward to a unique gig, and I assume a few free tickets to the rest of the weekend!
Anyway he was decent and i'll certainly be making an effort to see him again.
