"There's A Meetin' Here Tonight" by Joe & Eddie (only the first verse and chorus is HERE) is:

Breakin' up big rocks on the chain gang,
Breakin' rocks and soothin' my time.
Breakin' up big rocks on the chain gang,
Oh Lord I committed a crime.
Hold it steady right there while I hit it
I reckon that ought to get it.
Been workin', I been workin',
And I still got so terrible long to go.
