As a freshman I had an opportunity to listen to a talk by a member of the '55 team who ran a self-publishing firm. He exemplified Woody's practices: he got a list of the attendees ahead of time and memorized a few biographical details (stuff like location) and asked questions for those who stayed afterward. (He's how I learned about the idea of forced questioning.) He shared a couple good stories:
When Coach Hayes was fired, some hundred(s?) of his former players attended a party held on his behalf. He greeted each of them by name. And then proceeded to ask about their parents by name.
One of the services Coach would provide for his players was to provide a job reference. A backup player listed him as a reference on a job application in Cincinnati, and the prospective boss decided he'd call up Hayes. He was surprised when Woody refused to give the reference by phone, and doubly surprised when he showed up to give it in person.
