I sent a PM to Jon Bartlett who might be able to help.

Johnny Appleseed Grace (song)

Oh, the Lord's been good to me.
And so I thank the Lord
For giving me the things I need:
The sun, the rain and the appleseed;
Oh, the Lord's been good to me.
 
Oh, and every seed I sow
Will grow into a tree.
And someday there'll be apples there
For everyone in the world to share.
Oh, the Lord is good to me.
 
Oh, here I am 'neath the blue, blue sky
Doing as I please.
Singing with my feathered friends;
Humming with the bees.
 
I wake up every day,
As happy as can be,
use I know that with His care
My apple trees, they will still be there.
The Lord's been good to me.
 
I wake up every day 
As happy as can be, 
Because I know the Lord is there
Watchin' over all my friends and me
The Lord is good to me
