"Sin's A Good Man's Brother" is a song which was originally by Grand Funk Railroad. This song comes from a rare South African hard rock album called "Time To Suck" from 1971. It contains heavy guitars with screaming vocals that is on par with any UK underground rock act from that period. The album contains a great version of Deep Purple's "Into the Fire" and Black Sabbath's "War Pigs" among other covers.
