Truthful

Tell me it's not true Say it's just a story So did y' hear the story Of the johnstone twins? As like each other as two new pins Of one womb born, on the self same day, How one was kept and one given away? An' did you never hear how the johnstones died, Never knowing that they shared one name, Till the day they died, when a mother cried My own dear sons lie slain. An did y' never hear of the mother so cruel, There's a stone in place of her heart? Then bring her on and come judge for yourselves How she came to play this part.
