My all-time favorite work song is
Push Boat. It's an old American song sung by Jake Xerxes Fussell. I just love Americana music and this one tells a simple story of three guys (the singer, Pete and Lazy Sam) "goin' up Big Sandy" on a push boat. Wonderful story-telling, singing and music.
"Oh, the weather
The weather's mighty hot, boys
Blisters on my feet
Working on a push boat
To buy my bread and meat"
