I love Sammy Hagar (and am a huge Van Hagar fan), but this doesn't sound like typical Sammy to me. He's always been a straight shooter, but this comes across as passive aggressive, when Sammy is usually such a laid back guy who doesn't speak crap about anyone.
Since he's a third party, he really doesn't have any inside info, so the title of that article is misleading, and false. He's wrong about the new album being old stuff. They listened to old demos as part of the writing process from what I've read, but nowhere is it said that they are simply reusing any of them or aren't writing new material.
I am extremely optimistic about the new VH album, as the few things VH have written since VH3 have been great. I love Hagar, but the Chickenfoot albums are just sterile and uninteresting, and I'm dying for some real VH.
