Pynchon's narration of IV trailer = his Introduction?

[Doug Millison]

Anybody seen the text of Pynchon's narration of the book trailer video  
that's linked at the Amazon.com book page?  It would be interesting to  
read as part of an IV discussion, the way he discusses the story in  
the voice of Doc Sportello. He may even introduce some bits about  
Sportello that aren't exactly in IV, I'd have to listen to it again  
and compare to the IV text.

Very interesting to have what amounts to an introduction to the novel,  
in Pynchon's own voice, don't you think? I didn't think he would take  
part in the marketing of a book to this degree, but I'm glad he has  
done it this time.
