Willie Nelson didn't show up for a fundraiser in the Denver area Saturday (Aug. 18), TV station KUSA reported .
The fans gathered at Castle Pines Village were told that Willie, 79, was "suffering from breathing problems due to the high altitude and emphysema" and taken to a near by hospital.
No condition was available as of Monday morning.
Looks like the decision to cancel was made last minute: The TV station reports that Willie's backup singers did arrive at the venue, but he didn't.
Willie is scheduled for a show Tuesday (Aug. 21) in Dallas.
