This is a soul adaptation of a song from "Purlie," a 1970 musical based on a play written by the late great Ossie Davis. It is quite different from the version featured in the musical.
Part of what I find inspiring about this record is that it was recorded 40 years ago when Americans believed their world was crumbling around them. In times of great change things can often become violently combustible. It seems that in many ways we are echoing that era of the late 60s and early 70s right now. This song is a reminder that people made it through that time of strife. The key is to keep your hope alive, keep fighting the righteous fight, and keep pushing forward. Songs like this one can go a long way in feeding perseverance. Give it a listen.
