If you are in earshot of BBC Radio 4 or have access to BBC iplayer you can listen to this interesting biography of the great writer with Ian playing the voice of Roald.
It might also be of interest to Fan Editors wanting to grab sound snippets.
"Always take notice of omens" is one example that leaped to my ears.
"He has a pair of testicles the size of walnuts"....maybe not.
