Willie Nelson's band members are lucky to be alive ... according to the man who called 911 after their tour bus crashed last week in Texas.
As we reported, 3 of Willie's band mates were hospitalized after their bus crashed along I-30, hitting a bridge pillar, roughly 80 miles from Dallas ... and it was real bad.
Willie wasn't on the bus -- he's got his own private ride. The other bandmates are out of the hospital and recovering. Willie's tour resumes December 10th in Vegas.
