Yeah, Joe and Dave should be able to take a nap or two on this one it's getting more than it's share of bumping.
Like my original theory stated, in order to draw attention to Helmet and Testament they put UFA on the bill, but once they think they've reached the appropriate amount of publicity they pull them.
I think they should take this a step further and hold their National acts hostage.
Bring in a Testament and say, "UNLESS WE RECEIVE THE PURCHASE OF 100 PRESALE TICKETS BY 10PM TOMORROW, WE WILL BE FORCED TO PUT UFA ON THE BILL. DON'T MAKE US DO IT, WE NEED 100 TICKETS SOLD BY 10 PM TOMORROW OR THIS SHOW GETS IT!!!!"
