Willie Nelson had a stomach bug, but he also had a concert to perform. He didn't want it to stop the show so he walked out onstage at the Outlaw Music Festival in Charlotte, North Carolina. He was messing with the guitar straps for a minute, and then he left the stage.
WIllie came back and picked up his guitar, and then he left the stage again, as he tossed his cowboy hat in the crowd.
Unfortunately, Willie had to cancel the show, but he plans on doing a makeup show.
It's hard to take a sick day in the concert business, even if you're 85 years old.
Get well soon Willie!
