The former Beatles drummer tweeted Thursday that he was “surprised” by his positive test result.
On Thursday, however, the 82-year-old told fans: “I’m sure you’ll be as surprised as I was I tested positive again for Covid.”
“The rest of the tour is off,” he added, signing off with his trademark “peace and love.”
Remaining dates on the tour had been planned for California and Mexico.
In June, two members of his All Starr Band, Edgar Winter and Steve Lukather, tested positive for the virus, forcing 12 show dates to be rescheduled. These shows were originally planned for 2020.
