Recorded at Olympic Studios in a session produced by Margolis and featuring harmonica virtuoso Harry Pitch, "Just Loving You" had been released in January 1967 but did not reach the UK Top 50 until 29 June 1967. Even after peaking at No. 6 on 26 August 1967 "Just Loving You" remained in the UK Top 40 until the end of the year, and was reported to have accumulated UK sales of 625,000 in six months. Besides charting at No. 18 in Ireland, "Just Loving You" was a Top Ten hit in South Africa where sales reached 200,000 copies. The disc was released in September 1967 in the United States where it rose to No. 20 on the "Easy Listening" chart in Billboard and approached the mainstream Pop "Hot 100" chart. It rose no higher than No. 120 on the "Bubbling Under" chart. In January 1968 Harris made her only appearance on the UK album chart when her Just Loving You album reached No. 29.
The sustained interest in "Just Loving You" predicated a mild chart impact for her follow-up single "The Playground", released in September 1967. This reached its chart peak of No. 46 by 28 October 1967, the same week "Just Loving You" (which had dropped out of the Top 20 at No. 21) returned to the Top 20 for three more weeks. However she did score a substantial hit with her 5 January 1968 release, a remake of the standard "Anniversary Waltz", which spent eight weeks in the UK Top 40, peaking at No. 21.
