Apparently its been leaked that it is in order of appearance.....
The Mystery Jets
We Are Scientists
Maximo Park
Arctic Monkeys+Editors in London Dates

If thats true its pretty good but at the same time a bit of a piss take on Maximo Park given that there album is out, theyre doing well. It wouldnt be right to have Arctic Monkeys headliners when their album isnt out yet. One question...are all AM fans wankers?
