Task: Question Generation
Input (English): Passage: The audience response at Presley's live shows became increasingly fevered. Moore recalled, "He'd start out, 'You ain't nothin' but a Hound Dog,' and they'd just go to pieces. They'd always react the same way. There'd be a riot every time." At the two concerts he performed in September at the Mississippi–Alabama Fair and Dairy Show, 50 National Guardsmen were added to the police security to ensure that the crowd would not cause a ruckus. Elvis, Presley's second album, was released in October and quickly rose to number one on the billboard. The album includes "Old Shep", which he sang at the talent show in 1945, and which now marked the first time he played piano on an RCA session. According to Guralnick, one can hear "in the halting chords and the somewhat stumbling rhythm both the unmistakable emotion and the equally unmistakable valuing of emotion over technique." Assessing the musical and cultural impact of Presley's recordings from "That's All Right" through Elvis, rock critic Dave Marsh wrote that "these records, more than any others, contain the seeds of what rock & roll was, has been and most likely what it may foreseeably become."Presley returned to the Sullivan show at its main studio in New York, hosted this time by its namesake, on October 28. After the performance, crowds in Nashville and St. Louis burned him in effigy. His first motion picture, Love Me Tender, was released on November 21. Though he was not top billed, the film's original title—The Reno Brothers—was changed to capitalize on his latest number-one record: "Love Me Tender" had hit the top of the charts earlier that month. To further take advantage of Presley's popularity, four musical numbers were added to what was originally a straight acting role. The film was panned by the critics but did very well at the box office. Presley would receive top billing on every subsequent film he made.On December 4, Presley dropped into Sun Records where Carl Perkins and Jerry Lee Lewis were recording and had an impromptu jam session, along with Johnny Cash. Though Phillips no longer had the right to release any Presley material, he made sure that the session was captured on tape. The results, none officially released for 25 years, became known as the "Million Dollar Quartet" recordings. The year ended with a front-page story in The Wall Street Journal reporting that Presley merchandise had brought in $22 million on top of his record sales, and Billboard's declaration that he had placed more songs in the top 100 than any other artist since records were first charted. In his first full year at RCA, one of the music industry's largest companies, Presley had accounted for over 50 percent of the label's singles sales.
