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 Undermined the mountain side and the castle tumbled down One one one grain of sand A lover spoke an angry word that led to 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
