I do know that two of Elvis favorite songs was "Green, Green Grass of Home" by Tom Jones. That song is from the 70s. When Elvis heard it on the radio the first time he cried. He called George Kelin, the disc jockey, and made him play it over and over. Another one of E's favorites was "Mohair Sam". I forget when the song came out, but I heard that he liked it quite a bit.
