Rod Stewart shared with his audience why he had to cancel two of his Las Vegas residency shows at the last minute. Nearly a week after, the legendary singer told fans during his June 2 concert that he had a severe sinus infection that led to complications with his ears and eardrums. Rod admitted he probably should have gone to the hospital sooner, revealing that the infection left him unable to hear and affected his balance. Despite the setback, the 81-year-old returned to the stage at Caesars Palace, assuring fans that his voice was strong—even if he might “stumble a bit” during the show. Rod is set to continue his Las Vegas residency through June before returning for additional dates in August.
