DK and MK seem to be very stubborn, in my view it takes two to continue this odd relationship. But it may take only one step towards the other to clear that old conflict out. Ok, perhaps I don't know that much about their reasons and see that too simple-hearted although I went through a similar situation.
The impression that people attending a concert want to listen to the artist(s) seems to be antiquated, in 2007 I had the pleasure to be seated in front of a couple of chatterboxes. This kind of disrespect towards the artist and the rest of the audience is getting more and more common.
Anyway, I'll definitely visit a DK concert for the first time when he's en route again.
