In a quiet, yet not entirely unexpected move, Dillinger Four has been removed from the Fuck Yeah Fest lineup. All was revealed in a short addendum to this blog post, where it reads:

Dillinger Four & Partyline have both cancelled. Bummed. But D4 will be playing one show out here in Fall. We will be putting it on and will let you know when it will be.

As noted, Partyline has also dropped out of the fest, which will serve as the Explosion's final West Coast appearance.
