Letra de Keep A Knockin'

Keep a knockin´ , but you can´t come in. Keep a knockin´ , but you can´t come in. Keep a knockin´ , but you can´t come in, come back tomorrow night and try again. You said you love me, but you can´t come in. You said you love me, but you can´t come in. You said you love me, but you can´t come in, come back tomorrow night and try again.
