Hi, ddpro -
What language is the spoken part? - I'm guessing it's Korean, but I may be all wrong. If you can use this thread to post the other lyrics from the video, that would be nice. I wonder who the older woman is - she looks like the woman who played Grandma Walton. It's not, though - it's Jessica Tandy, and Hume Cronyn and John Denver are also in Foxfire, a 1987 Hallmark television movie.
Here's what I hear:

Now the stars is restin'
Settin' on the hill
Nothin' is soundin' but a whippoorwill;
Down in a hollow where the foxfire glows,
Dear Lord, give all your creatures there repose.
Day is done, dear Lord,
Tomorrow's sun, dear Lord,
Is sure to come,
Is sure to come,
Is sure to come;
We have your word, dear Lord.

(during the funeral procession)
Every shadow's shrinkin', shrinkin to the west,
The breeze comes a-sweeping
Across the fresh-mown hay.
Dear Lord, be with us through a newborn day.
Newborn day, dear Lord,
Oh, let it stay,
Oh, hear me pray, dear Lord.
