22、Elvis Aron Presley, often called “the king of rock music”, died on August 16th, 1977, at the age of forty-two. He left a great influence on popular music, and millions of fans. During his lifetime, Elvis sold more than four hundred million records. After Presley died, many of his records rose quickly. When Presley died, many mourners journeyed to Memphis, Tennessee, Presley's home, to pay their last respects. While most of these fans knew a lot about the songs of Elvis, few of them knew the story of how Elvis had his first record which was for his mother. He paid four dollars to a small Memphis recording shop, and recorded two songs. The songs were “My Happiness” and “That's Where Your Heartaches Begin”. Sam Philips, who owned the shop where Elvis made the record, liked Presley's songs. He said he would call him some day. About a year later, Philips did call and asked him to cut a record. This first record had “Blue Moon of Kentucky”on one side, and “That's All Right, Mama”on the other.
