BLACK SABBATH canceled its concert Saturday night (January 30) at the Rexall Place in Edmonton, Alberta, Canada just two hours before the sold-out “The End” tour show was supposed to start. Messages on the band’s official Twitter and Facebook feeds read: “Due to extreme sinusitis with Ozzy Osbourne, the shows in both Edmonton and Calgary [on February 1 at the Scotiabank Saddledome] have been postponed. Details regarding rescheduled dates will be announced as soon as they are available.”
