I think for 95% of Mark's career his playing has been unbelievable, and only in the last few years has that suffered, and he admits this himself. People have got so used to seeing Mark's playing as completely effortless and fluid, that when it slows down, like it has at the start of this tour, it is noticed, yes his energy levels have also slowed, but that down'st worry me, he has never had to be that kind of front man really. At the age he is now, his priorities have changed, which is fine, he sees himself as a songwriter, not a guitarist. I would want to be retired long before 70, but I am not Mark Knopfler!!! My guitar playing will never ever come close to his, so I think at times people can be hard on him.
