On July 1, 1958 RCA Victor released "King Creole - Volume 1" Three weeks later Billboard started to list the record on their "Best Selling Pop EPs Chart", where it had a run of 55 weeks and peaked at number one. It stayed there for a whopping 30 weeks! On the domestic market RCA Victor sold 1.4 million copies, which was honored in 1992 with a Platinum Award by the RIAA. Abroad the extended player was far less popular and sold no more than 200,000 units. Today the global sales of 1.6 million phyical copies equal 240 million paid streams of the complete extended player or 960 million paid streams of individual tracks. Commercially "King Creole - Volume 1" was a massive success. It became the second best selling ep of the king. The number one spot belongs to "Jailhouse Rock", which today is regarded to be the best selling extended player of all time.

The cover was designed with a (flipped) promo photo for the movie. The backside advertised the single "Hard Headed Woman" / "Don't Ask Me Why", which featured another two songs from "King Creole".

The ep is not available on the streaming platforms, because all songs can be heared on the album "King Creole" (1958).

The soundtrack was recorded on January 15th, 16th and 23rd 1958 at Radio Recorders in Hollywood/California. The sessions were produced by Walter Scharf and Phil Khagan and engineered by Thorne Nogar. The band consisted of Elvis himself (guitar) as well as Scotty Moore (guitar), Hilmer J. Timbrell (guitar), Bill Black (bass), Ray Siegel (bass and tuba), Neal Matthews (bass and guitar), D.J. Fontana (drums), Bernie Mattinson (percussion), Gordon Stoker (bongos), Hoyt Hawkins (zimbel), Dudley Brooks (piano), Mahlon Clark (clarinet), John Ed Buckner (trumpet), Justin Gordon (saxophone), Elmer Schneider (trombone) and Warren Smith (trombone). The harmony vocals were provided by The Jordanaires (Gordon Stoker, Neal Matthews, Hoyt Hawkins and Hugh Jarrett) and Kitty White (on "Crawfish"). On February 11, 1958 an additional session was held at the Paramount Soundstage in Hollywood/California. It was also produced by Walter Scharf and Phil Khagan, but engineered by Phil Wisdom. Elvis and Scotty Moore played guitar, Bill Black was on bass, D.J. Fontana on drums and Dudley Brooks on piano. Once again the harmony vocals were provided by The Jordanaires. The session had been scheduled to record "Danny" and "Steadfast, Loyal And True" as well as harmony vocals for "Lover Doll".

The title song of the movie was written by Jerry Leiber and Mike Stoller. To fit the location of the movie it was enhanced with brass, which sets it apart from other tunes of this kind. On January 15, 1958 Elvis recorded 18 takes of "King Creole", but because he didn't like the results he recorded 13 more on January 23rd. The final one became the master. It was also released on the boxed set "The Other Sides - Worldwide Gold Award Hits Volume 2" (1971).

Elvis performs this bluesy song very well. On January 15, 1958 he needed five attempts to do so. "New Orleans" was written by Sid Tepper and Roy C. Bennett, who also would provide many of the average movie tunes of the 1960s. Later it also would be released on the boxed set "The Other Sides - Worldwide Gold Award Hits Volume 2" (1971).

 "As Long As I Have You" was written by Fred Wise and Ben Weisman, who would become a main source for movie tunes in the following decade. In contrast to many of their later compositions, this one has quality and is performed very well by Elvis. It was done within ten takes on January 16, 1958.

Sid Wayne and Abner Silver wrote this nice popsong, which was taped by Elvis on January 16, 1958. Take number 7 is featured on this extended player, but the version on the longplayer included harmony vocals by The Jordanaires. They had been recorded in a separate session on July 19, 1958. The boxed set "The Other Sides - Worldwide Gold Award Hits Volume 2" (1971) also included the overdubbed version of "Lover Doll".
