From my own experience and learnings of recording oral histories, there is a relationship of trust that has to be developed and maintained before, during and after the recording. Then there is the technical stuff: don't wear bangles or noisy clothing; make sure the subject is comfortable and willing to stay the duration; ask leading questions, not ones that end in a 'yes' or 'no'; do your research. One of the most interesting instructions and something I've stuck to ever since is that you should never ask an interviewee to tell their story before you start taping. If you do, they will tell it to you in vivid, gorgeous detail. When you begin recording, your interviewee will be rehashing, editing and reciting and all that rawness is gone forever.
Anyway, most of the rules get thrown out the window at Pallinup.
I love the yarn below, because it is just so bloody funny ... a story of Old Salt's Dad, one armed poacher of legend, getting busted for undersized black bream in the 1950's.
