7.ARMY MAN: In 1960's G.I. Blues, Elvis didn't have to stretch too much to play a singing G.I. stationed in Germany. In the early 1960s, Elvis focused more on his film career than on live performances. After making G.I. Blues and its accompanying soundtrack, Elvis starred in Flaming Star, Wild in the Country and then Blue Hawaii. During that time, Elvis was taking in the Hollywood scene surrounded by a close-knit group of friends that became known as the Memphis Mafia, author Peter Guralnick noted in his 1999 book, Careless Love: The Unmaking of Elvis Presley. One member of the group, road manager Joe Esposito, said in the book: "None of us slept more than a few hours at a time. We lived on amphetamines. We woke at 5 o'clock each morning to report to the set, then spent the rest of our time screwing around." As the 1960s wore on, Elvis's star had begun to fade somewhat, as he was upstaged by the onslaught of the Beatles and the changing social climate. As Guralnick wrote: "There was no getting past the fact that the records were no longer selling as they once had, they no longer mattered as they used to. (Elvis) admired the Beatles yet felt threatened by them ... he, too, had once been in the vanguard of the revolution, and now he was embarrassed to listen to his own music, to watch his own films."
