Led Zeppelin - Think It Over lyrics

Think it over what you just said Think it over in your pretty little head Are you sure that Im not the one? Is your love real or only fun? You think it over, yes, think it over A lonely heart grows cold and old Think it over and let me know Think it over but dont be slow Just remember all birds and bees Go by twos through lifes mysteries You think it over, yes, think it over A lonely heart grows cold and old Think it over and think of me Think it over and you will see A happy day when you and I Think as one and kiss the blues goodbye You think it over, yes, think it over A lonely heart grows cold and old Think it over, over and over Think it over, over and over
