From Green Day’s facebook page:

“GREEN DAY POSTPONE FIRST THREE DATES OF UPCOMING NORTH AMERICAN CLUB TOUR AND CANCEL TORONTO APPEARANCE

LOS ANGELES, CA – SEPTEMBER 18, 2016 – Green Day regretfully must postpone three of the first four dates of their upcoming tour and must cancel the Toronto appearance, all due to illness affecting several members of the band and its crew. The postponed dates are: St. Louis, MO on 9/20, Chicago, IL on 9/21; and Detroit, MI on 9/24. The show in Toronto, ONT on 9/23, where they were due to appear at the World Cup of Hockey Fan Village will be canceled. Schedule permitting, Green Day will make up all dates but Toronto, and tickets will be honored at the new dates.
“We’re so sad to announce we have to postpone three shows and cancel Toronto,” said the band. “Many of us have been battling this infection for days on end to be ready, and it just got the best of us”
Fans who would like to obtain a refund can do so from their original point of purchase. Stay tuned to www.Greenday.com for more info on the new tour dates.”

We will keep you updated!
