Yes, Dan, it was I who annotated several volumes in the series - the BB King, Freddie King, and Gatemouth Brown. I was hired by the man who supplied the tapes to Charly, which were cassettes with absolutely no information. Whatever information I provided was what I was able to dig up on my own. I believe that these were originally radio broadcasts, taken off the air by a fan, and almost certainly not authorized by the artists.
