What about "Working On A Building," seems like a natural choice to me.

I'm working on a building, I'm working on a building, (hallelujah)
For my Lord, for my Lord,
It's a Holy Ghost building, it's a Holy Ghost building, (hallelujah)
For my Lord, for my Lord.

Or perhaps Nat Adderley's great number, "Work Song."

Bustin' rocks out here on the chain gang,
Bustin' rocks and servin out my time,
Bustin' rocks out here on the chain gang,
Cause I've been convicted of a crime.

Hold it steady right there while I hit it,
Well I reckon that ought to get it,
I've been workin', workin',
And I still got so terrible far to go.
