The musician had to finish a concert in Salt Lake City prematurely. According to his own statement, he suffered from altitude sickness.
The singer apologised that he was not able to finish the concert in Salt Lake City on Sunday evening (local time). Nelson announced a little later on his Twitter Profile.
As a reason, he stated that he had become ill in the 1300-meter-high city. "This is Willie. I am very sorry to have to cut the Salt Lake City performance short tonight. The altitude just got to me. I am feeling a lot better now and headed for lower ground", wrote Nelson.
According to concertgoers, Nelson left the stage after about half an hour after the start of the concert. Willie Nelson is a famous American country singer who has been around for over six decades.
