The Three of Us in The Dark Lyrics

(Carly Simon)
[ Lyrics from: http://www.cloverlyrics.com/e27637-carly_simon~the_three_of_us_in_the_dark_lyrics.html ]
The three of us in the dark
Where do I resist
One has to go
One is just a guest
One is all a fire
One is all a spark
But here I am with the two of you
The three of us in the dark

I didn't hear you walk in the door
You'd called to me years ago
I had heard
Your voice before
One is all a fire
One is all a spark
But here I am with the two of you
The three of us in the dark

The eerie sound of one lone fiddle
The wind is finding the tune
And you lying here in the middle
As innocent as the moon
Entangled in embraces that God will never see
Do you know me

Who am I talking about
It all gets so confused
And what would I do
If I had to choose
One is all a fire
One is all a spark
And here I am with the two of you
The three of us in the dark
