 Country music star Willie Nelson returned to the stage last night after being off the road for two weeks because of an unspecified illness. Nelson's Outlaw Music Festival tour kicked off two weeks ago with a roster of fellow stars that has included Bob Dylan, Robert Plant, Alison Krauss, Mavis Staples, and Maren Morris. But the 91-year-old Nelson did not perform until the tour and outgrowth of his traditional July 4th picnic shows made it to Camden, New Jersey, the night of the 4th. How's it going? Good.
