Peace in the Family, key of D on Blue Lion mountain dulcimer.
See for fun Rhett Walker presentation and the lyrics shown below:

We don’t want the hurting
We don’t want the war
Be the revolution
What are we fighting for

Feel the Spirit pouring down now
See the healing with your eyes
It's lightin’ up the darkness
That's how we rise
Let love run the streets
Let love run the streets
One love
Same blood
Peace in the family

Brother Sister
Love is all we need
Mother Father
We need peace in the family
We all live many different lives
You and me, the same inside
One love
Same blood
Peace in the family

We should come together
Throw out all the pride
Take the hate out the weather
Sun's gonna shine
Don't let them drown you out now
Don't let them cover up your eyes
We're coming out the darkness
We always rise
Let love run the streets
Let love run the streets
One love
Same blood
Peace in the family

Brother Sister
Love is all we need
Mother Father
We need peace in the family
We all live many different lives
You and me, the same inside
One love
Same blood
Peace in the family
