After working exclusively with producer/songwriter Tony Hatch following their 1964 breakout collaboration "Downtown", Clark had had her most successful single ever in the spring of 1967 with "This Is My Song", a Charlie Chaplin composition recorded by Clark with producer Sonny Burke.

The resultant These Are My Songs album was also produced by Burke with Hatch contributing only one track albeit the one selected as the follow-up single: "Don't Sleep in the Subway". Despite that single's success Clark proceeded to record her next album without Hatch's involvement again working with Burke except for the track "The Cat in the Window (The Bird in the Sky)" which was released as an advance single in August 1967.

"The Cat in the Window (The Bird in the Sky)" at #26 became Clark's lowest charting US single to that date and missed the UK Top 50 entirely, causing Clark to reunite with Hatch for a track to be added to her album as the title track and to serve as a second advance single. This track: "The Other Man's Grass is Always Greener" — which Hatch says contains "a lot of deep thought [and] a lot of philosophy... [Clark] enjoyed singing those kind of songs" — was musically similar to "Don't Sleep in the Subway" but failed to approach that hit's success, reaching only #31 on the Hot 100 in Billboard for the last week of December 1967 and the first week of January 1968. The song did best on the Easy Listening chart, where it reached a peak of number three. In the UK "The Other Man's Grass (is Always Greener)" - so entitled - spent six weeks in the Top 30 with a #20 peak on the UK chart dated January 16, 1968.

The original Billboard magazine review of the song raved that "The team of Clark-Hatch and Trent combines talents once again for this blockbuster rhythm item that should rapidly rise to the top. Well written material and winning performance."
