Just a quick one to give some of you an idea find the strum pattern out yourself
Song is tuned down a step and in Drop C I believe
So basically drop D tuning tuned down a step

D G
It's the Widow now that owns that angry plow,
C* G/B D
The spartan Mule and The Crippled Cow
D G
The fallow field that will yield no more,
C* G/B D
As the fox lay sleeping beneath her kitchen floor
D G
The stream can't contain such the withering rain,
C* G/B D
And from the pasture the fence it is leaning away
D
The clouds crack and growl
G
Like some great cat on the prowl
C* G/B D
Crying out, "I am, I am" over and over again
D/Db

The days grow short
G/C
As the nights grow long
D/Db G/C
The kettle sings its tortured song
D/Db G/C
As many petalled kiss I place upon her brow,
C G C G D
Oh, my lady, Lady I am loving you now
The winter birds have come back again,
Here the sprightly Chickadee
Gone now is the Willow Wren
In passing greet each other as if old, old friends
And to the voiceless trees
It is their own they will lend
The days grow short
As the nights grow long
The kettle sings its tortured song
As many petalled kiss I place upon her brow,
Oh, my lady, Lady I am loving you now
G D
And though all these things will change,
G D
The memories will remain
A G D
As green to gold, and gold to brown
A G D
The leaves will fall to feed the ground
A G D
And in their falling, make no sound
C G
Oh my lady
C G D
Lady I am loving you now
I've gathered all my money and I'm goin' to town,
To buy my lady a long and flowing gown
'Cause come tomorrow morning
We're off to the county fair
I'll find a yellow flower
And I will lace it in her hair
