I hope that someone can help me with this. Years ago I herad a song written by Leon Rosselson (I'm not sure that I"ve spelled that right). I've been looking for the tune and lyrics ever since. It's about a guy who works nights in a sausage factory and spends his days building a preposterous sculpture in his back yard. He absorbs no end of grief from family and neighbors for the latter activity. It is the only song I've ever heard which explores the nature of that wretched/beloved demon we call "creativity".

All I remember is the chorus:

Press screw. Turn. Lift.
Early shift and late shift
Every day the same routine.
Turning little piggies into plastic packaged sausages
To sell in the heliport canteen.

Could somebody help me to find this song, please?
