The music, it moves you, it flat out disproves you    In your unwillingness to sing   Just sit back, relax, let your ears pick up the slack   And realize that it's quite captivating      Knock three times let me know you're alone   Before I get up to open the door   You know I've been waiting patiently for you    To come back around      Don't attempt to shut it out (shut it out!)   The message is there so figure it out   The cadence of your body language seems to disagree   With the words that you so strongly want to believe      Knock three times let me know you're alone   Before I get up to open the door   You know I've been waiting patiently for you    To come back around      Knock three times..
