From the site:
Below is a peek at [Roben] Jones' wonderful research into these Presley sessions, in a terrific chapter called "From a Jack to a King." In particular, [her] prose not only reinforces that it was a crazy, magical time but also confirms Presley friend Marty Lacker convinced the singer to shun a scheduled Nashville date and try Memphis instead. We learn the core musicians like Cogbill, Reggie Young, Bobby Emmons, Mike Leech and even arranger Glen Spreen were blasé when learning of the booking, then thrilled to meet Elvis when he made his entrance, resplendent in a exceptional blue leather jacket, on the first night. On the other hand, most of the Presley entourage tagging along failed to impress any of them. The "Memphis Boys" also make no bones about who was in charge despite the presence of RCA executives, a subject that has strangely been a source of recent debate on this forum.
