Well, I love the song and the following is fairly close. Since Jean is known to frequent these parts, maybe she will correct any mistakes.

Cool of the Day
(Jean Ritchie)

   (Em)Now is the (A)cool of the (Em)day
   (Em)Now is the (D)cool of the (G)day(B)
   This (Em)earth is a (A)garden, the (Em)garden of my (A)Lord
   And he (Em)walks in his (A)garden
   In the cool of the (Em)day

My (Em)Lord, he (A)said unto (Em)me
Do you (Em)like my (D)garden so (G)fair(B)
You may (Em)live in this (A)garden if you'll (Em)keep the grasses (A)green
And I'll re(Em)turn in the (A)cool of the (Em)day

CHO

Then my (Em)Lord, he (A)said unto (Em)me
Do you (Em)like my (D)pastures so (G)green(B)
You may (Em)live in this (A)garden if (Em)you will feed my (A)sheep
And I'll re(Em)turn in the (A)cool of the (Em)day

CHO

Then my (Em)Lord, he (A)said unto (Em)me
Do you (Em)like my (D)garden so (G)free(B)
You may (Em)live in this (A)garden if you'll (Em)keep the people (A)free
And I'll re(Em)turn in the (A)cool of the (Em)day

Chorus
