There's (finally) an excerpt of Neil reading from Chapter Three of Ghost Rider over on Rush.com (click The Band, the Neil to find the page; I'd link directly to it, but the thing's in Flash). Now if they'd only get around to updating the rest of the site (the promised interview with Geddy and the questions from Big Al's Summer Extravaganza).
Tiny review: I expected a little more of a performance than an actual straight reading from the book. It was flat, as if he was reading something he was unfamiliar with. The multimedia stuff was ok, and the music sounded like a Laurie Anderson backing track, which was odd. I do hope that there's more of it to come, although I doubt it'll ever be a book on tape sort of title.
