The two albums precedent to Petula: These Are My Songs and The Other Man's Grass Is Always Greener had been primarily produced by Sonny Burke with Tony Hatch, the producer/songwriter who'd established Clark as a top recording star in 1964, contributing only one track to each album. With Petula Hatch again became Clark's exclusive producer overseeing all the album's tracks. Petula would prove to be the last Petula Clark album of original material produced by Hatch.

The first advance single from Petula: the Les Reed/Barry Mason composition "Kiss Me Goodbye" had reached #15 US in April 1968, becoming the first hit single for Clark produced but not written by Hatch. Of the eleven additional tracks which would comprise Petula, seven were written by Hatch and Jackie Trent. Hatch also had Clark cover "Days", "The Good Life" and "This Girl's in Love with You" and recorded Clark singing "Why Can't I Cry" which had been written by arranger Johnny Harris and wife Kim Clark. The song was also recorded by Tom Jones.

The Hatch/Trent composition "Don't Give Up" - described by Hatch as a homage to "Can't Take My Eyes off You" - was released as the album's second advance single in July 1968 and failed to sustain Clark's Top 20 comeback peaking at #37 on the Billboard Hot 100 becoming Clark's final US Top 40 hit.²
