At this point the people waiting for Art to come back remind me of myself in 2004 thinking "maybe this will be the year Barry Sanders realizes he made a mistake and comes out of retirement." It didn't happen, and neither will Art coming back to Coast. Sometimes a guy comes around who can't be replaced, and when his run is over, that's it.
That written, I did notice something several months back on a "Somewhere In Time" show there was a caller asking if Art was going to do some convention/expo/group wank thing and he mentioned that he doesn't like to travel and do those; nor did he want to do television or anything else that would take away from the show. He just wanted to make the show the best it could be, and that other stuff detracted. I was hoping someone in charge of selecting shows picked that one to wake up "traveling Jones" George, but I suppose I was reading too much into it.
