I'm just curious - do the main headliners usually start after the other stages close each night or do they compete with the other stages? I've been to festivals where they do it both ways.

The reason I'm asking is because I'm dying to see both Bjork and Jarvis Cocker and I hope they don't play at the same time.

I wish they didn't have to wait so long to put up the grids, but I understand it takes time...
