Given the following context:

Presley undertook three brief tours during the year, continuing to generate a crazed audience response. A Detroit newspaper suggested that "the trouble with going to see Elvis Presley is that you're liable to get killed." Villanova students pelted him with eggs in Philadelphia, and in Vancouver the crowd rioted after the end of the show, destroying the stage. Frank Sinatra, who had famously inspired the swooning of teenage girls in the 1940s, condemned the new musical phenomenon. In a magazine article, he decried rock and roll as "brutal, ugly, degenerate, vicious. ... It fosters almost totally negative and destructive reactions in young people. It smells phoney and false. It is sung, played and written, for the most part, by cretinous goons. ... This rancid-smelling aphrodisiac I deplore." Asked for a response, Presley said, "I admire the man. He has a right to say what he wants to say. He is a great success and a fine actor, but I think he shouldn't have said it. ... This is a trend, just the same as he faced when he started years ago."Leiber and Stoller were again in the studio for the recording of Elvis' Christmas Album. Toward the end of the session, they wrote a song on the spot at Presley's request: "Santa Claus Is Back in Town", an innuendo-laden blues. The holiday release stretched Presley's string of number-one albums to four and would become the best-selling Christmas album ever in the United States, with eventual sales of over 20 million worldwide. After the session, Moore and Black—drawing only modest weekly salaries, sharing in none of Presley's massive financial success—resigned. Though they were brought back on a per diem basis a few weeks later, it was clear that they had not been part of Presley's inner circle for some time. On December 20, Presley received his draft notice. He was granted a deferment to finish the forthcoming King Creole, in which $350,000 had already been invested by Paramount and producer Hal Wallis. A couple of weeks into the new year, "Don't", another Leiber and Stoller...
