(Buck Maxwell - Ruth Maxwell - Rosella Larue)      One, one, one grain of sand   One, one, one grain of sand.      Just one little grain of sand   Can change your life and ruin your plans   Undermine your house of love   Bring it tumbling down   One, one, one grain of sand.      Once upon a mountain top a castle stood   Carved out of rock and stone, iron and wood   Then one day a grain of sand grew into an iron latch   Undermine the mountain side and the castle tumble down   One, one, one grain of sand.      A lover spoke an angry word that left the tears   The tears led to a quarrel, love disappeared   That word was like a grain of sand   That undermined the things they've planned   It shook up the house of love   And brought it tumbling down   One, one, one grain of sand.      Just one little grain of sand   Can change your life and ruin your plans   Undermine your house of love   Bring it tumbling down   One, one, one grain of sand.      One, one, one grain of sand   One, one, one grain of sand...
