PAIN, BIG PAIN keeps right on hurting me you left me lonely as a boy can be   I'VE GOT TO smile so it don't show but everybody knows I'm wearing the smile of a clown   Laugh clown laugh clown I THINK that's what they say oh how long can I go on this way   Telling jokes all over town knowing all the while I'm wearing the smile of a clown   Sure I'm laughin' laughin' to keep from cryin' cryin'   But I'm just hidin' hidin' the hurt you left my darlin'   Why oh why must I go on this way you left me lonely only yesterday   I look in the mirror dear saw a face and a tear wearing the smile of a clown   Sure I'm laughin' laughin'...   I'm wearing the smile of a clown
