Clement actually wrote several of the tunes on that album, including the always popular "Dirty Old Egg Sucking Dog," but the biggest hit was that song about the folk-singers, "The One on the Right Is on the Left" (clip). It told the story of a promising singing group that faced difficulties because the members couldn't reconcile their differences.
Although the song is over forty years old, it carries a message that might still be valuable to some. It's pretty clearly spelled out in one of the verses:
'They were long on musical ability
Folks thought they would go far
But political incompatibility led to their downfall'
