“Knock Three Times” was written by L. Russell Brown and Irwin Levine. The song draws inspiration from The Drifters’ 1962 song “Up on the Roof.” It captures a similar lyrical flavor, focusing on tenement living and a secret romantic connection. “Knock Three Times” became a massive hit for Tony Orlando and Dawn. It reached No. 1 on the Billboard Hot 100 chart and sold millions of copies worldwide. The song’s popularity extended beyond the US, claiming the No. 1 spot on the UK Singles Chart. The lyrics tell the story of a man who falls in love with his upstairs neighbor. Too shy to approach her directly, he devises a plan: she should knock three times on the ceiling if she wants him, and bang twice on the pipe if not. The song beautifully captures the anticipation and longing of secret affection.
