I have an archive tape from the early 60's of a CBC radio interview with my great grandmother, who died shortly thereafter. My great grandad was a longtime politician, and the CBC wanted some reminiscences from her after he died.
I played the tape a few years ago at a family reunion. Here was the voice of an old woman from forty years back, remembering her childhood (and courting days)in Wales in the late 1800's. My seventy-five year old uncle had his year-old great grandaughter on his lap as we listened to the tape. For one marvellous moment we had seven generations of the family in one place.
