Enjoy the show.
I've only paid a brief visit to Calgary (a day or two, en route from the Rockies to Drumheller, of all places) and it was a long time ago but I have fond memories, especially of the view from the viewing platform in the CN Tower.
As I've said here before, BD is not an easy listen, especially for the first time, but, even with his limited vocal range and throatiness nowadays, he does offer "a helluva show", as one MK fan I know said of the recent Edmonton show, adding, "for a 70 year old" - a backhanded compliment, I guess, but a compliment nevertheless.
