The music, it moves you, it flat out disproves you nIn your unwillingness to singnJust sit back, relax, let your ears pick up the slacknAnd realize that it's quite captivatingnnKnock three times let me know you're alonenBefore I get up to open the doornYou know I've been waiting patiently for you nTo come back aroundnnDon't attempt to shut it out (shut it out!)nThe message is there so figure it outnThe cadence of your body language seems to disagreenWith the words that you so strongly want to believennKnock three times let me know you're alonenBefore I get up to open the doornYou know I've been waiting patiently for you nTo come back aroundnnKnock three times..
