American singer Andy Williams, 82, said he is ill with bladder cancer and is undergoing treatment.

The singer of "Moon River" released a statement Sunday following reports that he told the crowd at his show in Branson, Missouri, on Saturday night about his illness.

"You may have read or heard that I have bladder cancer. It's true and I'm currently undergoing treatment to deal with it," Williams said in a statement, according to CNN.

"I do have cancer of the bladder. But that is no longer a death sentence. People with cancer are getting through this thing. They're kicking it, and they're winning more and more every year. And I'm going to be one of them," Williams told the crowd according to the Tri-Lakes News.

Williams canceled planned performances this fall due to certain medical condition and the Moon River Theater has said he will likely miss his holiday schedule for the same reason, according to the Tri-Lakes News.

Williams is better known for his Christmas recording of "It's the Most Wonderful Time of the Year," and for hosting "The Andy Williams Show" in the 60's and 70's.
