These are the lyrics from Bascom Lunsford; odds are the one you heard is directly or indirectly from it. Lunsford says "I learned this song ... from Miss Lela Ammons, a girl fifteen years old in 1904, in Graham County, NC. I recall it now from memory but I've never heard it from other sources."

Oh! 'tis sad to be parted from those that we love
Strange faces we see every day
Each heart string of mine is broken in time
when I think of those dear ones at home.

Cho:
Goodbye, dear old stepstone, goodbye to my home
God bless those that I leave with a sigh
I'll cherish fond memories when I'm far away
When I think of those dear ones at home.

I stood on my door step at evening and morn
The wind whispered by with a moan
Fields may be whitening but I will be gone
To roam over this wide world alone.

I stood on my door step when school time was o'er
And I wished for the time to go by
Now it has passed and I stand here tonight
To bid this old stepstone goodbye.

from Pete Gilpin and George Stephens, Bascom Lamar Lunsford: Minstrel of the Appalachians (Stephens Press, Asheville NC: 1966). Lunsford recorded this commercially for Brunswick in the 1920s, plus several times later while recording for the Library of Congress. Woody Guthrie and Cisco Houston covered it for an Asch recording in the 1940s, and this (via its 1960s reissue on LP) is probably whence its more recent circulation.
