The lead singer has sinusitis
Black Sabbath was forced to cancel two shows in Canada due to Ozzy Osbourne's health problems. The shows on the 30th and 1st are yet to be rescheduled.
Two hours before the start of the show on the 30th, the band posted on social media: “Due to Ozzy Osbourne’s extreme sinusitis, the shows in Edmonton and Calgary have been postponed. Details about the new dates will be announced as soon as the band is available.”
