Barry Manilow is doing well after surgery, but says he needs more time to recover before appearing on stage.

The singer, who was scheduled to begin his Feb. 12-21 residency dates at Westgate Las Vegas, said that he will need to postpone the performances for now. The update arrives after Manilow announced back in December that would undergo surgery to remove a “cancerous spot” on his lung.

“I’m doing great and recovering very well after my surgery,” Manilow wrote in a statement shared to social media on Wednesday. “I’ve been getting exercise and spending some time in the studio, which has been fantastic.”

“With my doctor’s guidance and recommendation, however, we have decided to postpone my residency dates at Westgate Las Vegas from February 12-21 so I can stay focused on healing and getting ready for the tour that’s kicking off at the end of February,” he continued. “Having a few weeks to rest and prepare is what the doctor ordered!”

Tickets for the Vegas dates will be refunded. Manilow will return to the Westgate on March 26, 27, and 28, according to a rep for the singer.
