The Almanac Singers varied the verses a bit from concert to concert. Here are two versions:

Hard, Ain't It Hard
1
Hard, aint it hard
To love one who never did love you.
Hard, ain't it hard, ain't it hard, great god
To love one that never would be true.
2
It was late last night when my true love came home
He was a-knocking on my door
I got up in a fit of jealousy and I said
True love, don't come here anymore.
3
Hard, ain't it hard
To love one who never did love you
Hard, ain't it hard, great god,
To love one that never could be true.
4
The first time I seen my true love
He was a-knocking at my door
The last time I seen his hard-hearted smile
He was lyin' dead on the floor.

Chorus

5
Don't go to drinkin' and gamblin'
Don't go there your sorrows to drown
This hard liquor place is a low-down digrace
It's the mesnest bad place in this town.

Chorus

Hard, Ain't It Hard
Almanac Singers (Guthrie, Lee Hays, Millard Lampell, Pete Seeger)

1
There is a house in this old town,
And that's where my true love lays around,
And he takes other women right down on his knee
And he tells them a little tale he won't tell me.
2
Hard, ain't it hard, ain't it hard
To love one that never did love you?
It's a-hard, and it's hard, ain't it hard, great god,
To love one that never will be true/
3
First time I seen my true love
He was walkin' by my door.
Last time I seen his false-hearted smile
He was dead on his coolin' board.
4
Don't go to drinkin' and gamblin',
Don't go there your sorrows to drown,
That hard-liquor place is a low-down disgrace,
It's the meanest damn place in this town.
5
Well, who's goin' to kiss your ruby lips,
And who's goin' to hold you to their breast?
And who will talk your future over
While I'm ramblin' in the west?
