<P> Over the next 15 months, the trio would release five singles, tour extensively across the South, and appear regularly on the Louisiana Hayride; it was the biggest rival to the Grand Ole Opry at the time . They had originally auditioned for the Opry in October 1954, but they failed to impress the people in charge, or the audience, and were not invited back . Several biographers cite Jim Denny, talent agent at the Opry, as the man who told Presley that he should "go back to driving a truck". </P> <P> The trio would record at Sun together until November 1955, when Phillips sold Presley's contract to RCA Victor for $40,000; it was, at the time, the highest sum ever paid for a recording contract . Sun had permission to keep pressing the singles until January 1, 1956, and RCA Victor released Presley's first five Sun singles nationally . In January 1956, Presley recorded "Heartbreak Hotel", his first RCA Victor single . He would return to Sun studios regularly over the next few months, visiting with Phillips and meeting many of the label's new artists . </P> <P> Although Presley never officially recorded for Sun again, he was caught on tape during an impromptu jamming session on December 4, 1956 . Presley had arrived during a Carl Perkins recording session, which also featured a young Jerry Lee Lewis on piano, and a new artist named Johnny Cash watching on . During a break in recording, Presley sat at the piano and began to sing along with Perkins, Lewis and Cash . Phillips kept his tape recorder running, and, seeing an opportunity to promote another of his new acts, he arranged for a reporter to cover the event . The recordings would eventually be known as "The Million Dollar Quartet". </P> <P> During Presley's tenure at Sun Records, he recorded two demo recordings in Lubbock, Texas: "Fool, Fool, Fool" and "Shake, Rattle and Roll", which were released for the first time by RCA in the 1990s . These are not considered Sun recordings . </P>
