Yeah, I emailed the festival and they said to keep checking because they haven't heard about any changes. I asked them 3 times if, in fact, the Presidents would be playing. They kept emailing me "Keep checking the site". Don't know why they couldn't tell me yes or no.
Ya, I noticed that they are still listed on ticketmaster, and their website says they are back in the US for some of May, but playing in France the weekend after Sassquatch. I sure hope their there, I would really like to see them live.
Presidents are definitely playing, and if you haven't seen them recently check out some reviews of their shows - especially this one from LA where Weird Al and Wayne Kramer from the MC5 - theroxyonsunset.com/still-the-presidents-after-all-these-years/ - definitely one of the best live bands playing the festival, their Seattle album release party was crazy and their new is awesome.
