Hozier into Chapell into Foos. If Foos have dropped out though, this early in the day id have thought they would replace rather than shift everyone up.
I don't think there'll be any clashes. Bludfest this year used the big stage at the foot of the bowl for all the big acts, and in the 20 minute set up time between them, they'd put a much much smaller act on a small stage far back beyond the edge of the bowl, beyond the trees.
