Having read B.B.'s autobiography Blues All Around Me I knew most of the stuff about his early life and career but there are plenty of other gems in it, including interviews with fellow blues guitarists Buddy Guy and Peter Green paying tribute and acknowledging his influence on their sound.
The most moving bit though is right at the end where a tearful B.B. stands next to the Governor of Mississippi in the state legislature as 15th February is declared B.B. King Day. You can imagine what's going through his mind in a building that as a young man he would probably have been beaten up, if not worse, just for entering. B.B.'s isn't the only eye it brought a tear to.
