Sub for sure... them headlining would be so underwhelming. But I would bet on both NBT and FF not being there as their tour schedule is already quite busy and it just doesn't look very likely logistics-wise...
Yeah, looks like it will sell out earlier then usual. No surprise really as very good value, when you think of the cost for Kasabian/Blossoms Warchild/Brits concert this looks fantasic value.
There is enough international goodwill towards  Gazans to allow them to rebuild quickly and effectively. And if hamas stop the rocket attacks then they will be left alone to do it.Â
