Slight thread creep.When I worked in Woodbridge back in the 60s, I lived in "digs" at Old Barrack Road, in the house where Fitzgerald once lived. Fitzgerald's niece, Barbara Foster, who inherited the house had all sorts of memorabilia, including a/the(?) manuscript of the Rubaiyat. At the time I was into rock'n'roll more than Folk, and if the Hasted connection was ever mentioned, it didn't stick in my memory.
Another old folkie on his way to Valhalla - he had a "good innings", though, and a full and varied life.
Salve!
