Diamond recorded "Kentucky Woman" as his last hit single for Bang Records. Released in October 1967, it reached number 22 on the U.S. pop singles chart, number 58 on the Australian charts, and number 6 on the Canadian charts. The song was mixed in monophonic, which is the common version heard on all Neil Diamond compilations featuring original Bang singles. The only known stereo mix was done in 1978 for a Frog King/Columbia House album called Early Classics, which has never been released on CD.

Recorded by Deep Purple with a vastly different instrumental feel, if not vocal line, it was their second single release in 1968. It managed to reach #38 on the Billboard Hot 100, #21 Canadian RPM charts, and #27 on the Australian Singles Chart where it was released as a double A-Side with "Hush."

The single version is an edit of the album version and is four minutes and four seconds in length. A remastered version appears on the 30th anniversary album The Very Best of Deep Purple and runs a full four minutes and forty five seconds.

Deep Purple played "Kentucky Woman" live on tour in 1968 and 1969, even after Ian Gillan joined the band in the summer of 1969. It has never been on Deep Purple's set list since.

Waylon Jennings also released a version on his 1968 album, Only the Greatest.Gary Puckett & the Union Gap included a cover of the song on their first album, Woman Woman.
