I'm sure David and Jon aren't the same friends they were 30 years ago but I don't see why they wouldn't still be friends today.

What I find odd about David is that he seems to really dislike meeting fans. I've had it happen to me, and I've read about it quite a few times with other people. Clearly "David Bryan" isn't a household name, one would think he'd be happy to be recognized by fans since the only ones who know him are diehards.
