After having to drop off the initial three shows on his Outlaw Music Festival Tour last weekend, country legend Willie Nelson canceled his appearance at the next scheduled stop on the tour. Nelson did not perform at Wednesday night’s Outlaw Music Festival date in Virginia Beach, Virginia. The show still went on with scheduled sets by Bob Dylan, Alison Krauss and Robert Plant, and Celisse, with Willie’s son Lukas Nelson once again filling in for his ailing father.

Willie’s Instagram shared the news of his June 26 show cancellation: “Willie Nelson will not be performing at tonight’s show in Virginia Beach. We expect Willie to return to the tour shortly. Bob Dylan, Robert Plant and Alison Krauss, and Celisse will perform as scheduled. In addition, Lukas Nelson and Family along with some special guests will play his own set which will include Willie’s classics and other songs.” No specifics have been provided about Willie’s illness. The next stop on the Outlaw Music Festival Tour is Friday night in Syracuse, New York. (Taste of Country)
