Later this month Keith Urban will have surgery to remove a polyp from his vocal cords. He has had to cancel appearances where he would need to sing multiple songs - those shows will be made up next year. He will be honoring his commitments for one-son performances, so we will see him next Wednesday at the CMA's. (YAY!) He, along with Vince Gill and Brad Paisley will be honoring Glen Campbell at the big event Wednesday, and I know Keith wouldn't want to miss honoring someone he calls a "guitarist (I LOVE that!). Someone who has probably been one of his biggest influences.
Best of luck to Keith with the surgery.
