If I wasn't familiar with Curtis Mayfield and heard a gospel choir perform this gospel song, I might have thought it was "folk" too!

Ironic anecdote alert. I was living in England from '79 to '81 and used to listen to Jim Lloyd's "Folk on II." He once introduced a song by saying "now, here's (name of group) with an American work song." They started to sing acapella:

Early in the morning factory whistle blows,
Man rises from bed and puts on his clothes,
Man takes his lunch, walks out in the morning light,
It's the working, the working, just the working life.

Through the mansions of fear, through the mansions of pain,
I see my daddy walking through them factory gates in the rain,
Factory takes his hearing, factory gives him life,
The working, the working, just the working life.

End of the day, factory whistle cries,
Men walk through these gates with death in their eyes.
And you just better believe, boy,
somebody's gonna get hurt tonight,
It's the working, the working, just the working life.

The Factory, by Bruce Springsteen (It sounded good acapella)
