Lyrics:

Hey girl, whatcha doing down there?
Dancing alone every night, while I live right above you
I can hear your music playing, I can feel your body swaying
One floor below me, you don't even know me, I love you
Oh, my darling
Knock three times on the ceiling if you want me
Twice on the pipe if the answer is no
Ooh, my sweetness, means you'll meet me in the hallway
Twice on the pipe means you ain't gonna show
If you look out your window tonight
Pulling the string with the note that's attached to my heart
Read how many times I saw you, how in my silence I adored you
And only in my dreams did that wall between us come apart
Oh, my darling
Knock three times on the ceiling if you want me
Twice on the pipe if the answer is no
Oh, my sweetness, means you'll meet me in the hallway
Twice on the pipe means you ain't gonna show

Oh, I can hear the music playing
I can feel your body swaying
One floor below me, you don't even know me, I love you
Oh, my darling
Knock three times on the ceiling if you want me
Twice on the pipe if the answer is no
(I love you, I love you, I love you)
Oh, my sweetness, means you'll meet me in the hallway

Twice on the pipe means you ain't gonna show
