Tony Orlando & Dawn - Knock Three Times 1971

　邦題『ノックは三回』は当時驚異的にヒットした憶え易い曲だ。当時は恋人同士の合図なのかなぁと漠然と考えていたが、よく歌詞をみると（明るい節回しではあるのだが）アパートの部屋の真下に暮らす女性へ片思いを寄せる唄であることがわかる。

Hey girl what you doin' down there
Dancin' alone every night while I live right above you?
I can hear your music playin'
I can feel your body swayin'
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
Oh, my sweetness Means you'll meet me in the hallway
Mmm, twice on the pipe means you ain't gonna show

If you look out your window tonight
Pull in 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

(* repeat)

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

(* repeat)

　ＰＶをみて見ると、トム・ジョーンズ風の胸毛を強調したラテン系男性であることがわかる。このグループだが、もっと有名なヒット曲"Tie a yellow ribbon round the old oak tree"でも知られている。
