It appears that the song was only released as a single in Southern Africa, although it did appear on the b-side of the German pressing of ‘A Sign Of The Times’ which notes Tony Hatch & his orchestra in smaller type after Clark’s name as the artist. The South African pressing does not give this credit. This was the 3rd of 5 of Petula’s SA hits that Hatch had a hand in writing.

Pet Clark’s Where Did We Go Wrong is one of the greatest performances of a great pop song of the rich 60’s. Raw emotion………Strange that it was only released as a single in South Africa.. if you aren’t familiar with it, give it a listen…
