I have been singing this for some years, I don't know if this is the original, but this is it

Who'll be the Lady and Who'll be the lord
When we are in the love for one another
Who'll be the lady and Who'll be the lord
In the light that's coming in the morning

Chorus
Sing John Ball and tell it to them all
Now is the day that is dawning
I'll crow like a cock
and carol like a lark
In the light that's coming in the morning

Eve be the lady and Adam be the lord
When you are in the love for one anotherAnd the light that's coming in the morning
Eve be the lady and Adam be the lord
In the light that's coming in the morning

Chorus

Labor and spin in the in the fellowship you're in
Labor and spin, in the love for one another
Labor and spin in the fellowship you're in
And the light that's coming in the morning

Chorus

Labor and stay in the fellowship I say
Labor and stay in the love for one another
Labor and stay in the fellowship I say
And the light that's coming in the morning

Chorus X 2
