Sadly, as more and more vetreans, from all sides, pass on, you now have a very priviledged opportunity, as I'm sue you are aware. Eric is right, be prepared to listen, even if itching to get to the next topic/question, as the story will unfold in its own time. The question you were about to ask next, may well be answered in the dialogue, allowing you to modify the next question, if required, to gain more detail.
I, for one, look forward to whatever you are able to post, as you will be writing an historic account from one who was there.
Good luck, and I hope you are able to gain lots of info.
