Barry Manilow abruptly pulled the plug on his Lexington, Kentucky, concert Tuesday night — just 41 minutes before the music legend was scheduled to take the stage.

The 83-year-old “Copacabana” singer announced the sudden cancellation on X, leaving disappointed fans at Rupp Arena scrambling for answers.

“Due to unforeseen circumstances tonight’s show in Lexington has been rescheduled,” Manilow wrote.

No explanation was immediately given for the last-minute decision.

Rupp Arena assured ticket holders that they will not lose their seats, saying all previously purchased tickets will be honored once a new date is announced.

The sudden cancellation is especially concerning because the Lexington concert had already been postponed once before.

Manilow was originally scheduled to perform at the arena on March 9, but that show was delayed after the Grammy winner underwent surgery for lung cancer.

The legendary entertainer later revealed that he feared his famous singing voice might never return following the frightening health battle.

During an emotional June interview with Good Morning America, Manilow admitted he was devastated after struggling through his first sound check following treatment.

“I did my first sound check about a month ago and I didn’t sound like me at all,” he said. “I just couldn’t believe that it’s over.”

“That is really upsetting,” he added. “Because I don’t want it to stop.”

Manilow has since announced that he is cancer-free and said he “can’t wait” to get back onstage — as long as his voice allows him to continue performing.

For now, the reason behind Tuesday night’s cancellation remains a mystery.

Manilow is still scheduled to perform Wednesday night in Cincinnati, Ohio, though fans will likely be watching closely to see whether that concert goes forward as planned.
