Honey, I'm Home: Mercury's Shania Twain canceled her Oct. 6 and 7 Rock This Country Tour dates in Manchester, NH and Albany, NY, respectively, following doctor's orders to rest her voice after contracting a respiratory infection. "The concert dates are unable to be rescheduled due to Shania Twain's current touring schedule," reads a message on her Facebook page. "All tickets will be refunded at point of purchase. Shania Twain apologizes for any inconvenience this may cause her fans and greatly appreciates their understanding." The tour resumes Friday (10/9) at the Videotron Centre in Quebec City.
