Offered is a nice copy of 1954 Sun Records 223 45 RPM 7-Inch Single of Elvis Presley's “Mystery Train” and “I Forgot to Remember to Forget”. Sun Records released the single of “Mystery Train” in August of 1955 with “I Forgot to Remember to Forget” on side B. Later that year, in November of 1955, after they purchased Elvis' contract from Sam Phillips, RCA Victor purchased the master records from Sun and released “Mystery Train” again that month, followed by the release of the additional four Sun singles in December of 1955. “Mystery Train” is considered to be the recording that gained Elvis recognition as a country music star and was ranked #77 on Rolling Stone magazine’s “500 Greatest Songs of All Time.” The offered Sun Records single 45 for “Mystery Train” (223) contains matrix numbers which appear in the dead wax areas, with “45-U-156x 20” on side A and “45-U-157x 20” marked on side B. Also included is a later "SUN Records" paper sleeve. The record measures 7 inches in diameter and presents with moderate scuffing and a number of scratches. Good condition.
