There seems to be a family of songs called "...MEAN THINGS HAPPENING..." or "...STRANGE THINGS HAPPENING..."

John Handcox's recording called THERE IS MEAN THINGS HAPPENING IN THIS LAND appears on "Field Recordings, Vols. 10-11," Document CD #5600, 1998; and on "Songs for Political Action: Folk Music, Topical Songs and the American Left," Bear Family 10-CD set #15720, 1996. From a sound sample:

... in this land
But the union's going on,
And the union's growing strong.
There is mean things happening in this land

On the eighteenth day of May the union called a strike
But planners [or "planters"?] and their bosses throwed the people out of their shack
There is mean things happening in this land.
There is mean things happening in this land....

Blind Joe Taggart recorded STRANGE THINGS HAPPENING IN THE LAND. It is on "Complete Recorded Works, Vol. 2 (1929-1934)," Document CD #5154, 1994. I listened to a sound sample, but I found it nearly all unintelligible (except for the refrain, which is also the title).

Charles Haffer Jr.'s recording of STRANGE THINGS HAPPENING IN THE LAND appears on an anthology of songs collected by Alan Lomax called "The Land Where the Blues Began," Rounder CD #1861, 2002.

...please let our vessels be.
The Kaiser said to Wilson, "Keep your vessels off of the sea.
If you put them on the stream,
They'll meet my submarines."
There's strange things happening in the land.

The Kaiser kept on destroying every vessel he could see.
Oh, he treated us so [mean?]....

Jazz pianist David Berkman recorded MEAN THINGS HAPPENING IN THIS WORLD. Authorship is credited to Woody Guthrie, C. Kenally, J. Kenally, and K. Kenally.

Sister Rosetta Tharpe wrote and recorded a lively gospel song called STRANGE THINGS HAPPENING EVERY DAY. Sleepy LaBeef and Rev. Cleophus Robinson also recorded it.

...You must learn to quit your lying.
There are strange things happening every day.
If you do right to the line
You can live right all the time
There are strange things happening every day....

...There are strange things happening every day.
On that last great judgment day
When they turn some folks away
There are strange things happening every day.
Oh, every day (every day), every day (every day),
There are strange things happening every day.
Oh, every day (every day)....

Etta James wrote and recorded STRANGE THINGS HAPPENING.

...Strange things happening every day.
Oh, every day (every day), every day (every day),
There are strange things happening every day.
The love that you refuse
Some other man can use.
Strange things happening every day.

You never miss your water until your well runs dry.
Strange things happening every day.
I won't be satisfied....

Percy Mayfield wrote and recorded a blues song called STRANGE THINGS HAPPENING. Chicken Shack, Junior Parker, Sonny Rhodes, and several others also recorded it.

Learn to love me or leave me, either one you want to do. (2x)
Because strange things is happening. Baby, something might happen to you.

If you know you don't love me, why don't you let me be? (2x)
Because it's better to be without you than to live in misery.

Midnight caught me crying. Even daylight caught me crying, too....

Michelle Willson recorded STRANGE THINGS ARE HAPPENING EVERY DAY, which is credited to Elmore James. I think this is a mistake; it should be Etta James:

...I found me someone new.
I'm really through with you.
Strange things are happening every day....
