In 1969, Shelby Singleton bought Sun Records. He began a long search of the Sun catalogue, browsing through more than 10,000 hours of tape. At the same time, Singleton licensed much, if not all, of the Sun catalogue to the British Charly label for reissue in Europe. As a result of Singleton's and Charly's searches, a portion of the session came to light. This was issued in Europe in 1981 as "Charly/Sun" LP #1006 "The Million Dollar Quartet", and it contained 17 tracks, focusing on gospel/spiritual music from the session.
