After Mumfords were announced this is effectively the next announcement to where we are now from last year. I think McFly were added as secret guests later, so really there doesn’t look to be much more for the two main stages.
The reintroduction of the Seaside Stage/Bandstand could change that a bit, but while our local festival goers reckon it’s geographically possible, there’s been nothing from the organisers to suggest it’s happening.
