chord for a song

Does anybody know the chords for the song "Somebody's Knocking" by Terri Gibbs. This is a 1981 song. It is classified as country music. I found the lyrics, but I'm having troubles finding the chords. The song Starts out:

Somebody's Knocking should I let him in
Lord it's the devil would you look at him
I've heard about him but I never dreamed
He'd have blue eyes and blue jeans

As I went through the song I've noticed that there appears to be several lines missing. The song stays a pretty steady beat with a mello sound.
My wife has been walking around singing this song, but she only sings a few lines. The song came about when we were remembering when she was pregenant with our daughter.
She had a difficult pregnancy and we almost lost our daughter.
The baby was mean in the womb and even meaner now that she's out.
