You've probably seen this () already, but it's funny how he imitates Mark at 2:02. "Hello David ..."
By that way, I've writtten do David yesterday and got a very nice email back. I don't want to post it here for privacy reasons, and David didn't want to go into (legal) details anyway, but he seems to regret the fact very much that they hardly talk to each other and he still hopes for a "Hollywood ending". He says he really doesn't know why that's not on the table for Mark.
Personally, I wouldn't want them to reanimate Dire Straits or anything, I'd just want them to get along with each other.
