Some of the Bruce Eder timeline seems a little off. I knew Owen and Ruth (who became his second wife), in Edinburgh in the mid-sixties, and I'm sure I remember him reminiscing about the kibbutz then. I left Edinburgh in early 1967, and when I met Owen again in 1970, he was running a small delivery service - "Hand Transport", or something similar, was its name.
In 1993, he earned an MA with Honours in Scottish Ethnology. His thesis was 'The political influences behind the folk song revival in Britain, c 1950s-1960s'. He was with the European Ethnological Research Council for a while.
