For an ole' music/guitar aficionado like me, to see him play Lucille up close and live was a thing of beauty.
Wife and I saw him play in Atlanta a few years ago. George Thorogood opened for him. During BB's set, he had Thorogood come up and play with him. At one point Thorogood turned to the crowd and said, "I'm playing with BB. I'm going to enjoy every second of it."
That pretty much sums it up.
