原曲收錄於1931年舞台劇「Everybody's Welcome」，後因電影「北非諜影」走紅。

鄧麗君於1986年11月2日「Music Fair」中演唱片段，作為介紹「時の流れに身をまかせ」的引子。

You must remember this
A kiss is still a kiss
A sigh is just a sigh
The fundamental things apply
as time goes by

And when two lovers love
They still say I love you
On that you can rely
No matter what the future brings as time goes by
