Do we think fontaines big enough for main or headline castle? With all the other leaked headliners from other fests it may be comes a little clearer of who we could get . So my guess would be
common
Prodigy
Bloc Party
Pulp
castle
Travis
Fontaine
Basement jaxs
I imagine the crowd for Hoziers set would be awful for him because it will be made up of Travis' fans. Of which, I imagine, very few care about Hoziers music.
Despite not caring for Hozier myself I really do hate to see the energy get drained out of a set by a sh*t audience waiting for someone else.
