Foo Fighters have been forced to reschedule two Canadian shows, including their September 4 show at Rogers Place in Edmonton and their September 6 show at Scotiabank Saddledome in Calgary. The Edmonton date has now been moved to October 22, while the Calgary date has now been moved to October 23. This news comes after Dave Grohl lost his voice following the band’s September 1 concert at Safeco Field in Seattle. Previously purchased tickets will be honored at the new dates and refunds are also available at point of purchase until September 25.
