Gilstrap was a backup singer for Stevie Wonder and also the singer for the Good Times theme song. I heard this on a compilation of old school music. It's from a 1975 album that did well but I don't think this particular song charted. Anyway I certainly never heard of it.

"When the snows fall and the white winds blow, the lone wolf dies but the pack survives."
Winter is Coming

Now this is the Law of the Jungle—as old and as true as the sky; And the wolf that shall keep it may prosper, but the wolf that shall break it must die.
As the creeper that girdles the tree-trunk, the Law runneth forward and back; For the strength of the Pack is the Wolf, and the strength of the Wolf is the Pack.
