Contrary to fan speculation,[2] "Can't Forget You" was written specifically for Sonia by Stock Aitken & Waterman (SAW) and thus was not initially offered to, nor recorded by, Kylie Minogue.

"[6] Gary James of Entertainment Focus said almost the same thing: to him, "Can't Forget You" is "unmistakably a SAW production" and a "mid-tempo bop", but considered that it was "slightly more downbeat and mellow than [the previous single]".

[10][11] On the overall Eurochart Hot 100 compiled by the Music & Media magazine, it reached number 51 in its second week out of a five-week chart run.

[12] In Australia, "Can't Forget You" barely made the top 100 on the ARIA singles chart, peaking at number 98.

[13] Following the underperformance of Donna Summer's "Love's About To Change My Heart", the surprisingly poor chart showing of "Can't Forget You" has been cited as among the first significant signs of SAW's looming commercial implosion over the following 12 months.
