Uh oh...Not sure what caused this. Not much to go off of here besides what people are saying in the video comments. This video was apparently recorded the second time Willie tried to start his show after a first walk off. It's cited he looked disappointed rather than angry, maybe a bit of both, perhaps that his health is on the decline and he was unable to perform? Not sure what to say here really other than, if it is illness related, I hope he gets well very soon and gets back out on stage in front of his fans. I can't imagine he'll stay sidelined for very long. #WillieStrong
