New show added yesterday: Tucson, AZ (which is neither the capital nor the largest city in Arizona.) Still no Memphis (and Memphis is the largest city in Tennessee).
By the way, every time I see on the Van Halen website that a new show has been added to the tour, it always gives the date the show was added as the day before the date it's posted on the website. For example, I checked the list yesterday and there was no new date, but I checked the list today and there was a new date, but it says that the show was added on October 4, which was yesterday!! So either it's always the next day after a new concert is announced before the website gets around to updating the tour list, or they can't keep track of what day it is.
