Willie Nelson was forced to cancel a fund-raiser appearance in the Denver area Sunday night because he was having trouble breathing and was taken to a local hospital.

Nelson was to appear at a fund-raiser for the Dumb Friends League that was being held in Castle Pines Village, which is located 21 miles from Denver.

According to 9NEWS in Colorado, an announcement made to the crowd said Nelson was "suffering from breathing problems due to the high altitude and emphysema." One of the organizers of the event said Nelson was taken to the hospital.
