Hi Knopflerlondon. Several days ago I spoke with a friend who works as an usher for three theaters in Minneapolis. She had put in to work Mark's concert at the Orpheum Theater on Aug. 30 there, so has been keeping her eye on whether it is sold out or not. She told me that at this time, there are still a lot of tickets available, but she thought pretty expensive, too.
I hope you are able to get the tickets you would like.
