I will never forget hearing him being interviewed on Woman's Hour many years ago and describing a visit he made to a windmill (or something similar) situated on the top of a cliff.
I'm not sure if there's a recording of it available anywhere (if so, please do listen to it!), but it should go down in history as one of the BBC's great broadcasting moments. The interviewer - and, I'm sure, everyone listening - was spellbound by the tale.
