I Listen Close lyrics

I unlocked your side
It got dark and we went north
Trying to peek through driving snow
And I listened to you low
Outside the wind got fast and cold
And made a tiny sound, the ghostly Blow
You sang low, I listened close
I tried to join you in your note
The 3 parts surprised us both:
We 3; you and me and the Blow!
(it will be grey when we get home
I listen close, you keep me warm.)
