Well the book offers a lot of info... a little too much... that is allready a first hint that it is all bullocks.
He gives the studio times and the amount of takes on all known and unknown Sun songs, great but not real.
Then there is the strange story about two men who nobody has ever heard of, that would have seen the notes of Marion Keisker. They were not allowed to photocopy it but they wrote down the info they saw... yeah, right...
Then he gives times and playlists for every gig Elvis, Scotty and Bill did... Have you ever heard Scotty keeping a diary about all the gigs they did?... Me neither, so again: bullocks!
The writer is someone no one knows, he is now actually dead, found drowned in the river the Sceine in Paris... Weird story but true, according to Trevor from Elvis The Man And His Music.
So, it is the same as with Joe Pizza
, another attempt to get us all excited about nothing!
