Maybe the measure of a song is how many people see fit to shape it to their own musical styles, kind of like mining.

Stevie Wonder imagined the song as a Motowny bit of danceable social protest in the 60s:

An English socialist rock band with the appalling name The Redskins recorded a jazzy rockabilly version.

And you can’t overlook the Swedish death metal band Momento Mori’s swinging version from 1993.

And there are thrash metal, hip hop, folk, a cappella and other versions, that maybe we’ll get to another day when we’re deeper in debt.
