This won't go away. Seems Dire Straits could capitalize on this and get the reunion tour going in Canada. http://www.crtc.gc.ca/eng/com100/2011/r110121.htm
They could, for sure, but I don't think anything has changed as far as Mark is concerned since John Illsley mentioned it (a reunion) a year or two back. And personally I think a DS reunion would be a major disappointment. Dire Straits means a certain sound, synths, keyboards, even sax (an instrument which should be confined to jazz or Bedroom Classics Vol. 3), long, drawn out solos, etc. To force Mark out of his current world of folk and ethnic instruments and into the DS world - just wouldn't work. And as if he would do it for the money ... The other ex-members surely wouldn't have minded, I'm sure.
An NHB reunion, though ... That would have been amazing. That's setting where I feel Mark thrives the best.
Sorry, way off topic ...
