Black Prairie - Single Mistake chords

Single Mistake – Black Prairie

Capo on 3

Intro:
D – G – C – C 

D        G           C            C        (etc.)
It has to have a perfect melody
I am going to sing him to sleep
When the words are perfectly placed
I am not worried about a single mistake.

Bridge:
Am - C -      (Walk the base note from the last note of Am to the C)

I am practicing to get it right
Every note we read or sing tonight
When the words are perfectly placed
I am not worried about a single mistake

It has to have a perfect melody
I am going to sing him to sleep
And when the words are perfectly placed
I am not worried about a single mistake
