Tim, wonder if you're aware that Jack Hemingway was the Honorary Fundraising
Chair for the Ezra Pound Association's effort to preserve the Pound
birthplace?  He gave a reading a few years ago from "A Movable Feast," no
doubt the sections to which you refer.  During a QA afterwards he was asked
whether he considered Pound caustic or otherwise disagreeable and he replied
that Pound seemed just the opposite: affable, kind, generous.  Asked whether
he thought Pound was in fact "insane," he said Pound was always "different,"
and the line defining "differrent" from "insane" is often very vague.
Granted, he didn't meet Pound later in life, but thought this might be of
interest.
