Singer-songwriter Keith Anderson will undergo minor vocal cord surgery later this month to correct a voice problem that has resulted in the cancellation of his January and February tour dates. Anderson’s physician, Dr. C. Gaelyn Garrett, recommended the surgery and has ordered vocal rest for the singer. “I look forward to Keith returning to normal voice use after that time,” she said. The surgery will take place at Nashville’s Vanderbilt Medical Center. In a written statement, Anderson said, “I’m grateful to be able to take this time off during the dead of winter, a typically slower time on the touring schedule. I certainly look forward to hitting it full throttle in March.” His new single, “She Could’ve Been Mine,” debuted this week on Billboard‘s country chart.
