Counterfeiting has also been issued to "cash in" on the ever growing record collecting market. One major example is bootleggers have cloned copies of Elvis Presley's early singles for Sun Records since original copies starting changing hands amongst music fans for hundreds (and then, thousands) of dollars. Some who produce these even do so with the wrong material. For example the song "Heartbreak Hotel" which was never released on Sun, as by the time Elvis first heard it, prior to ever recording it, he had moved from Sun to RCA Victor. Rare releases by The Beatles such as their album with the butcher cover, fan-club only released Christmas records and early demonstration discs issued by EMI are also examples of product reproduced by counterfeiters due to their high value to collectors.
