I forget, is Mike Patton the really whiney one who can't hit a note? God I hate that vocalist. The other one is okay, but not so much my cup of tea. Glad you're excited about it, though, hope it's a good gig!

I think you mean Chuck Mosley, their first vocalist. He's still going. His vocals have improved a bit, but sometimes still can't hit his notes properly. I always wondered why FNM got him in the first place. The only thing his voice does for me is to take me back to the 80's, as he's got that kind of vibe, but apart from that I always thought Chuck's vocals were dire.
Mike is the one that hits all his notes, heh.
As for the OP, I heard they are still on top, if not better form than before, so you're going to have a blast! It's almost as if they never went away apparently. Have fun!
