Nick, I don't know. There is a link on the site to an email address that is answered by a lawyer doing pro bono work for the guys. I'm just trying to help spread the word.
What I do know is that legalese is often difficult to decipher, even for lawyers, and what passes for entertainment attornies down here is not always top-notch. Did they sign a bad deal? I don't know, but I'd like to see them have a fighting chance to defend themselves.
Also, you know that many lawsuits are often "bullying," where the plaintiff ask for the moon, puts the squeeze on defendants who cannot really afford legal representation, and pressures them to settle for less. If you cannot at least represent yourself (and this is a civil matter, where you do not have court-appointed lawyer guarantees) then you lose.
I also know that Brian's no babe in the woods. He's been in the business since he was a teenager (in his 50's now), he spent years with the Neville Brothers who could write volumes about getting screwed by the business, so I can't imagine he's naive.
Porter, Jr. should know better than anyone about the dark side of the business. Sehorn and Toussaint worked the Meters over pretty good back in the day. I don't know Russell Batiste at all, but he comes from a prominent N.O. musical family--he's heard the stories, too. I doubt any of them signed anything blindly.
