I wasn't going to say anything about this, since it would shatter our perception of GNR, but I've been told by "sources close to the situation" that Dizzy is playing Pittman's parts and that Pittman is playing Dizzy's parts. It seems they can't handle their own, so they're covering for each other.
Personally, I'm not sure I can ever look at those two hacks the same ever again.
Sorry to be the bearer of bad news.
