Out of the Blue的詞曲創作人為Delta Goodrem，以下是其歌詞：
Out of the blue, you suddenly appear
Without warning, you took my breath away
And I thought I knew you, I thought I knew
What we had was good, it was real
But you took a different road
And you left me lost, out in the blue
Now I'm standing here, in pieces
Trying to find my way back home to you
Out of the blue, you suddenly disappear
Without warning, I'm left here on my own
And I thought I knew you, I thought I knew
But now I don't know what to do
Out of the blue, it's such a shock
And now I'm crying in the dark
Trying to find my way back home to you
You said you loved me, and now you don't
You said you needed me, and now you've gone
It's so hard to let you go, yeah
And I'm hoping that one day soon
I'll hear from you, that you're coming back to me
That you'll be standing here beside me, out of the blue
And I still love you, still love you baby
It might not be today, it might not be tomorrow
But one day, yeah
Out of the blue, we'll meet again somewhere
In a new light, maybe in some different time
And when we do, baby it will be out of the blue
It will be out of the blue.
