Just read the review of Tunzi's book "Sessions III".
When I first read the book, I was somehow disappointed becuase I hoped for more and better pictures.
It's in my shelf for a year or so now and I must admit: this book is really great. first, it has over 600 pages - that's a hell of a work!
But the main thing is: you can find there a n y t h i n g.
There is no gap (if youcompare it to Jorgensen), there is a complete bootleg-list, the highlights sections gives you a hint what might be released in the future, and there's a complete list to each session that provides you with the info where you can find the outtakes ....
so, in the beginning, my focus was on the "rehearsal" section too much - and because there is no evidence yet that these recordings really exist, I was a little disappointed. But you mustn't reduce Tunzi's book on these 2 pages only! The session-details including the overdub session logs are really great work!
Thank you, Mr. Tunzi!
And I'm really looking forward to a wonderful photo-book called "Elvis Between And During Takes"
