Finally, the title song of Hair, the irreverent and brash credo of penniless hippies, reached Number 4 in a happy version by a well-dressed, freshly scrubbed group that would later be cloned as television’s Partridge Family. The Cowsills were a bunch of youngsters and their mom, who all made some nice recordings and had three hits in their brief career. Theirs was one of the most appealing flashes in the pan in show business history, though their version of the song “Hair” would likely give shudders to fans of the play. Happily for The Cowsills, the vast majority of the people who have heard “Hair”, have heard their version of it. For the Cowsills, unfortunately, it was three hits and you’re out; after “Hair” they were heard no more.
