Just in case you missed it you can catch Jim Naughtie's interview with Jad Adams and Tony Benn in the comfort of Tony's home, here.
Jad sifted through 12 million words of diary notes to produce his latest book Tony Benn, A Biography which is the fully revised and updated version of his 1993 classic.
The interview focusses on the process of diary keeping and maintaining accuracy as well as the somewhat daunting task faced by the biographer to make sense of it all.
I'd be lying if I told you that Tony Benn, A Biography isn't a tome. But you have the tried and tested hand of Jad Adams to thank for taking it down from 12 million words to something like 230,000. Pretty generous of him, really.
