Hmm, well... I spoke too soon.
I chatted up one of our directors, who has some connections to many of the folks interviewed in the Market Wizards books, and he said that after the book was published Tudor-Jones made a concerted effort to avoid all publicity. Anyone, including himself, in the Tudor organization that appeared anywhere in the press was fined $1,000, which went to his Robin Hood Foundation.
That's probably why you haven't found anything on the 'net. I've heard of several caes where they later regretted doing the interviews. Some of these guys just don't like publicity. And really, if you're not looking for money or selling something, who needs it?
