But if Mark wanted to play a huge charity concert for his fans he would do it. He obviously doesn't want all the pomp that would surround such an ad hoc show. It does not need the end of tour to spawn something different. He knows he can pack any music hall in the UK for a one-off gig. It is his choice and to me, he has chosen....not to:-)
Maybe as he gets older he is keeping the DS stuff in the show simply because it doesn't need rehearsing. The band members then only concentrate on the 2 or 3 new songs in the set plus tightening up the works on the last few years worth of additions. We all get old and we aren't as progressive as we used to be, we get tired, we get long in the tooth and I have seen some of that in Mk lately. It is a natural progression in life:-)
