What I liked about the book is that it offers the chance for the author
(Bobby) to provide more detailed/thought out/complete accounts of the events.
As well, there are some bits of business that were not included in the shoot video, and vice versa.
His delivery is golden, too.
Piper did a shoot with Highspots around the time his book came out.
I suspect that Higspots realized how close the interview was to the book and stressed several times in the write-up that the interview contains material
not in the book and that historians & fans will want to add both to their collection.
I got through roughly half of the DVD set and estimate that about 4-7% was different from the book.
Also, I'm a Piper fan, but the interview just wasn't overly interesting to me.
Part of it may be that Hot Rod jumps in and out of character - almost even telling parts of the story in kayfabe
(he does that even more in his book).That really contradicts the whole idea of a "shoot" interview.
Can you imagine if George Steel did his shoot in character?
At least you'd still understand more of what he says than Steiner.
