Tracy Pitcox, president of Heart of Texas Records, says that the 83-year-old singer was admitted to the critical care unit of Summit Medical Center in Hermitage, Tenn., on Thursday, July 2. Ferlin had an accelerated heart rate and possible pneumonia and doctors were treating him for chronic obstructive pulmonary disease. Tests were to be performed on Friday, July 3, and through the weekend. Now, Tracy reports that Ferlin has been moved to a private room and could be released later this week if he continues to improve. Ferlin is best known for his smash hits like “Wings of a Dove” and “Gone.”
