The original Temptations version of this song is one of my all-time favorites, but Al Green's version, which initially appeared on his 1971 LP "Gets Next to You", blows it out of the water. As far as I know, this live version is only available on his 1997 box set, but it's worth the price of admission alone. Absolutely dripping with sexual tension & near-religious fervor, you won't soon forget it.
