Willie Nelson, circa 1980. It was his "Willie Nelson and Family Live" tour (my favorite live album) at the Wheeling Civic Center in Wheeling, West Virginia. We had OK seats, but for the encore, I weasled my way up front and had my chest pressed up against the stage (I don't remember any security). Between two songs, Willie was shaking people's hands, and when he came to me, I shook his hand and asked if I could have his headband. Willie took it off his head and graciously placed the bandana in my hand! Shortly thereafter, during one of his songs, someone handed him a pint of whiskey. He took a swig and then walked over and handed it to me for a swig! I then handed it back to him. Crazy! I was 20 years old. I've loved him and his music ever since.
And that live album is magnificent. His interpretations of the songs and placement/order of each are brilliant! At the time, I didn't know what a "concept album was, but it's a great one!
