嚴格來說, 這並不是秋霞姐的頭一張單曲收錄曲. 她的頭一張單曲名為 Our last song together, 1975年3月錄製完成(B面的Where are you為小坂明子的あなた). 但因在其後她在一項香港流行歌曲比賽中, 以這首 Dark side of your mind 拿到"最佳作曲"與"最傑出表演"兩個獎項, 她的第一張專輯(大碟)亦以此為名, 而且, 此前的單曲都是翻唱曲, 因此 Dark side of your mind 便被視為她的正式出道歌曲.
Dark side of your mind
Loneliness is the price I paid
For having loved you stuck by you
Crying my eyes our everynight I prayed
To see you back and call me a fool
Happiness is what I gave away
For having loved you stuck by you
Drying my eyes I would wait for you
To take me back in your arms again
I don't care if you have someone on the dark side of your mind
I only need you to love me like before
I don't care if you have someone on the dark side of your mind
Just let me be the one you'll kiss tonight
