Oddly enough, first time I became aware of BB King was through U2, watching Rattle and Hum in the late 80s.
I remember him saying that people looked at him and went "Here he is, a 62 years old, and look what he's trying to do"
I wonder if he knew he'd still be at it over a quarter of a century later...
I do hope he recovers and keep on singing the blues for at least another decade.
