According to www.duranduran.com:
Duran Duran have been forced to cancel tonight's show (Tuesday, December 2) in Dallas, TX, scheduled to take place at the Nokia Theatre, because the band's keyboard player, Nick Rhodes, is still suffering from a very serious inner ear infection and doctors have told him that he is not allowed to travel.
Tickets for tonight's show will be fully refundable from the point of purchase.

Probably more like lack of ticket sales.
Tin ear?
No, actually it's been going on for a few days now. They had to cancel their US opener in San Antonio last night also.
Just see duranduran.com for the whole story.
And tonight's show in Tulsa OK was canceled too. I had 1st row seats to the San Antonio show the other night and didn't find out until showtime that it was canceled (and I drove down from Dallas to see them).
