June Tabor was prominent in university folk life.
The singer Ian Giles knows lots about the relatively recent (ie last few decades) folk past. Why don't you come up to Oxford for a weekend? I suggest the Nancy Kerr James Fagan gig at the Oxford FC, 11th July and for the inevitable sessions later that night and on the Sunday night at the Half Moon. You will get the chance to talk to many people active in the scene now and in the past.
