The first recording of "This Is My Song" was made by Harry Secombe, with Wally Stott responsible for arranging and conducting. Secombe himself found the lyrics risible; several takes were necessitated due to his bursting into laughter when he tried to sing the line: "I care not what the world may say". Despite the eventual UK release of Clark's version as a single, "This Is My Song"'s appeal was strong enough to sustain two versions high on the chart. Secombe's version debuted at number 44 on 25 February 1967 (the second week Clark's version was number one) to rise as high as number two on the chart dated 1 April (which featured Clark's version at number eight). (Clark's previous UK #1 song, "Sailor", had also had a rival version, in that instance by Anne Shelton, which had reached the Top 10. Wally Stott, who'd regularly produced Clark for the Polygon label in the early 1950s, had also overseen the Shelton recording.) Secombe's version of "This Is My Song" was included on the album "Secombe's Personal Choice", an April 1967 release whose chart peak of #6 in May 1967 bests that of both the Petula Clark albums which parented the song. Besides selling over 300,000 units in the UK, Secombe's version of "This Is My Song" also became a hit in Australia (#6), Ireland (#20) and South Africa (#15).
