Actually it' a call & response song, that I think dates back to slavery times, maybe, not sure, but I do know it's an old, old song.
More verses used are (according to SONGS OF ZION songbook...a great hymnal to ad to your collection of you don't have it already)
- Ain't no harm to keep your mind... (something like that I think)
- Can't hate your neighbob in your mind, if you keep it...
- Makes you love everybody with your mind, when you keep it...
- The devil can't catch you in your mind, if you keep it...
- Jesus is the captain in your mind, when you keep it...
