Barry Manilow is canceling more shows amid his treatment for lung cancer.

On Thursday, Manilow cut his performance at the Westgate Las Vegas Resort & Casino short after just 40 minutes on stage, citing “technical difficulties.”

Later, the 83-year-old announced that Friday and Saturday nights performances would be canceled as well.

“We’re very sorry, but we have to cancel tonight and tomorrow’s performances,” a statement on the “Mandy” singer’s Instagram page read. “Due to technical and vocal problems, we’re unable to put on our show.”

Fans were told in the comments that refunds for the canceled shows would be issued automatically.

Manilow’s representatives did not immediately respond to The Independent’s request for comment.

The pop icon has been performing in Vegas for his “The Hits Come Home!” concert residency since May 2018.

The news comes just weeks after he was forced to cancel his show in Lexington, Kentucky, hours before he was due on stage.

“Due to unforeseen circumstances tonight’s show in Lexington has been rescheduled,” a statement shared on Manilow’s X account read. A specific reason for the postponement was not shared.

The singer revealed his diagnosis with lung cancer in December last year, crediting his doctor with detecting it early during an MRI scan.

He underwent surgery to remove a tumor on his left lung, postponing his Las Vegas residency and several planned tour dates to recover.

Speaking to People in March, Manilow described the ordeal as “a nightmare,” but said he has also been able to find some positives amid an otherwise difficult time.

“I’m one of the lucky ones; I don’t have to have chemo, radiation and all that stuff,” he said.

“This made me stop and think about: Have I done what I wanted to do, and have I made people happy? Have I been a good friend?” he told People. “All of those cornball things that I’ve read for all of my life, I started to think about that, too. It really did stop me in my tracks.

“And the answers are yes. And as a matter of fact, there are more yeses than I ever thought.”

The Grammy-winning artist’s career has spanned over six decades. In that time, he’s released more than 30 studio albums, including 1978’s Even Now, which features his best-known hit “Copacabana,” as well as three other major singles: “Even Now,” “Can’t Smile Without You” and “Somewhere in the Night.” His other top hits include “Mandy,” “Somewhere Down the Road” and “Could It Be Magic.”
