Singer/songwriter John Prine has been diagnosed with lung cancer, the Associated Press is reporting. Prine, 67, is said to have an operable form of the disease. From a statement posted on his website, the singer said, “I’ve been diagnosed with non-small cell carcinoma of the lung. Doctors here in Nashville have caught it early, and it is operable. They see no reason why I won’t fully recover.”

Prine will undergo surgery next month, thus leading to the postponement of two upcoming shows in Louisville. Prine still plans to play his scheduled shows in Greensboro, NC on December 6 and Charlotte, NC on December 7.

John Prine emerged from Chicago’s folk scene in the 1960s and is known for hits such as “Angel From Montgomery,” “In Spite of Ourselves” an “Illegal Smile.” In 2010, Prine was honored with a tribute album that featured contributions from the likes of My Morning Jacket, Bon Iver, Conor Oberst and more.
