I saw him once in OKC when I was working up there and even got to meet him backstage before the concert. Also met Crystal Gayle that night too as she was the opening act.
Also saw him in Vegas with Dolly. They both came out and sang a few songs together, the she did a set, he did a set and then they finished the show together. Might be the best concert I ever saw.
Bet that was awesome to see I would love to see Dolly one day!!
