Francis recorded "My Heart Has a Mind of Its Own" at Radio Recorders studio in Hollywood CA over three different sessions on July 9, 25, and 31, 1960 with Jesse Kaye and Arnold Maxin acting as producers; Gus Levene arranged the orchestration and conducted. Jack Keller brought one of the LA tapes back to New York for a Sax & Guitar overdub at Olmstead Studios. Artie Kaplan and Al Gorgoni were brought in for the sax and guitar overdub.

Several takes from these sessions are still extant. The original MGM K 12923 single utilized Take 49 (recorded July 31, 1960) but two weeks into release this was replaced by Take 37 (recorded July 25, 1960) at the behest of Francis and the song's writers.

"My Heart Has a Mind of Its Own" became Francis' second consecutive A-side to top the Billboard Hot 100 reaching #1 on the chart dated 26 September 1960 and holding there the following week. The single also marked Francis' final appearance of the R&B charts at #11.

In the UK "My Heart Has a Mind of Its Own" reached #3.

On 18 October 1960, Francis recorded a German-language version of "My Heart Has a Mind of Its Own" entitled "Mein Herz weiß genau, was es will" which would remain unreleased until 1988.

Unlike Francis' precedent #1 "Everybody's Somebody's Fool", "My Heart Has a Mind of Its Own" did not become a C&W crossover hit for Francis herself but the song was subsequently recorded by several high-profile C&W songstresses beginning with Connie Smith on her 1966 album Downtown Country. In 1971 Smith's version was included on a compilation release which was entitled My Heart Has a Mind of Its Own.

The most successful country version was by Susan Raye in 1972 which hit Billboard's Top 10 Country Singles. Debby Boone made a slightly less successful hit of it in 1979, peaking at #11; Boone subsequently made less successful bids for C&W chart success with remakes of the Connie Francis hits "Breakin' in a Brand New Broken Heart" (#25) and "Everybody's Somebody's Fool" (#48).
