Elvis Presley cemented the status of "Blue Christmas" as a rock-and-roll holiday classic by recording it for his 1957 LP "Elvis' Christmas Album". Presley's version is notable musicologically as well as culturally in that the vocal group the Jordanaires (especially in the soprano line, sung by Millie Kirkham) replace many major and just minor thirds with neutral and septimal minor thirds, respectively. In addition to contributing to the overall tone of the song, the resulting "blue notes" constitute a musical play on words that provides an "inside joke" or "quail egg" to trained ears. "Blue Christmas" was also included on a 1957 45 EP (Extended Play) entitled "Elvis Sings Christmas Songs" (EPA-4108), which also included "Santa Bring My Baby Back (To Me)" on side one, with "Santa Claus Is Back in Town" and "I'll Be Home for Christmas" on side two. Presley's original 1957 version was released as a commercially available single for the first time in 1964. This single was also a hit in the United Kingdom, reaching No. 11 on the British singles chart during the week of 26 December 1964.
