I had the privilege of seeing B.B. King at my college alma mater shortly after I graduated there, in the mid-90s. In retrospect, I wish I could have attended that show with "older ears" but it still left a lasting impact. I think what impressed me the most was his sense of humanity - his presence and energy just WAS. I cannot remember what he played that night, but I still remember it.
During the second set, B.B. had a chair brought out for him. He said "Folks, when you get to me MY age, you've earned the right to sit down for the second set."
B.B., here's wishing you a permanent gig with God's own house band, and a really comfy seat...rest well and play on...
