《Sister》的歌詞如下：
Sister, you're my sister
You're the only one I need
Sister, you're my sister
And I'll always love you
Chorus:
But you must never know
The things I've done for you
I've tried so hard to find
A way to make it real
And now I've found someone
Who's just like you in so many ways
And now I can make you see
What I've been feeling all along
Sister, you're my sister
And I'll always love you
But you must promise me
You won't let it show
You must never let them know
The secret that we share
Sister, sister, sister, sister

I've given all my life to him
And now he loves me too
And I don't want to hurt you anymore
I want to be with him and you

Now that I've found someone
Who understands me like you do
I want to make it real, yeah, yeah, yeah, yeah, yeah, yeah, yeah, yeah (x7)
