“I’m heartbroken,” Stewart told his 1.2 million Instagram followers.

Due to sickness, Rod Stewart postponed a stop on his The Hits tour this weekend.

The Grammy Award winner, 78, announced the news to his 1.2 million Instagram followers, claiming that he had a “viral infection” that affected his throat and singing voice ahead of his appearance at A Day on the Green, an Australian food, wine, and music event.

“Hello, my friends,” he began his statement. “I’m devastated that I’m failing my fans who purchased tickets to A Day On The Green. I was told late this morning that I have a viral illness and that my throat is too inflamed to sing.”

“I’m only human and get sick occasionally, just like you. My greatest joy is performing for you, so I’m doing everything possible to recover and return to the stage!” Stewart continued.

He tweeted a Live Nation notice confirming the cancellation and revealing that Cyndi Lauper and Jon Stevens were supposed to join him onstage. “An additional announcement on the concert arrangements will be made early next week,” it said.

After being in remission from prostate cancer for two years, the Gasoline Alley performer takes his Vegas residency on the road for the tenth time in 2021. He had to stop singing for nine months after doctors had to cut into his throat muscles to remove thyroid cancer in 2000.

“When I woke up in the hospital, the doctor said, ‘Don’t worry, your voice will be back in six months,’” he told The Telegraph the following year. “Six months had passed with no voice. Seven months without a voice. No voice for eight months. I could communicate but not sing.”

“It only recently returned to its former grandeur, about four weeks following the operation. It’s not as strong as it should be right now, but it will be because I keep singing and singing and singing,” Stewart elaborated.
