I live living the land of the free and I like how it feels when you lean on me Ever since you wondered into my back yard I've dropped my resistance and lowered my guard You've got the pieces of my heart all in a row Knock one down and the whole thing goes The domino theory of love It only takes a shove I fall....you fall We've got to keep our defenses up That's the domino theory of love The game of romance is a balancing act Two steps forward and one step back Take a liberty, give a little ground Next thing you know you'll be sliding on down When it comes to sorting out our hearts and our minds We're just a couple pushovers standing in line. The domino theory of love It only takes a shove I fall....you fall We've got to keep our defenses up That's the domino theory of love When it comes to sorting out our hearts and our minds We're all a couple pushovers standing in line. The domino theory of love It only takes a shove I fall....you fall We've got to keep our defenses up Or we'll all fall down together It only takes a shove I fall....you fall We've got to keep our defenses up
