"(You're the) Devil in Disguise" is a 1963 single by Elvis Presley which was written by Bill Giant, Bernie Baum and Florence Kaye. It was published by Elvis Presley Music in June 1963.
The song peaked at No. 3 in the US on the Billboard singles chart on August 10, 1963 and No. 9 on the Billboard Rhythm and Blues singles chart, becoming his last top ten single on the Rhythm and Blues charts. The single was certified "Gold" by the RIAA for sales in excess of 500,000 units in the US.
In 1963, when the song was debuted to a British audience on the BBC television show Juke Box Jury, celebrity guest John Lennon voted the song "a miss" stating on the new song that Elvis Presley was "like Bing Crosby now". The song went on to reach No. 1 in the UK for a single week.
Bill Porter engineered the song for the Elvis Presley recording session on May 26, 1963, at RCA Studios in Nashville. "(You're the) Devil in Disguise" and its flipside, "Please Don't Drag That String Around", was recorded for a full-length album that was scheduled for release in 1963, but RCA chose instead to release the album piecemeal on singles and as soundtrack album bonus tracks.
Bass singer Ray Walker, of the gospel vocal group The Jordanaires (who also worked as Presley's backing vocalists for much of his career), is featured in the song, singing the repeated phrase in a deep voice, in order to represent the devil: "Oh, yes, you are," before the song's fade.
The recording appeared on the 1968 RCA Victor compilation Elvis' Gold Records Volume 4.
