BB King was my gateway to the blues, via his great album Live at the Regal. I saw him live once, at the Academy of Music in New York on a bill with the J. Geils Band in 1973 or so. An amazing show.
I just read on Wikipedia that King’s favorite singer was Frank Sinatra, who similarly died on May 14th.
Sweet Little Angel is a delightful song, full of life and generous good spirits. On a sad day, I get joy, and everything.
