<P> The composers of this song , L. Russell Brown autobiography THE QUINTESSENTIAL HITMAN. and Irwin Levine , were thinking of the song Up on the Roof and they wanted to write a song with that kind of lyrical flavor , about tenement living . In the song , the singer has fallen in love with a woman who lives in the apartment directly below him but has no clue as to her interest , so he asks her to respond by either knocking three times on the ceiling ( yes ) or banging twice on the pipe ( no ) , and the chorus includes sound effects of the two choices . ( However , the song never states her response . ) </P>
who sings knock three times on the ceiling if you want me
L. Russell Brown Irwin Levine
