《Knock Knock Twice》的歌詞如下：
Knock Knock Knocking on the Door
Twice, Twice, Twice, Oh Lord
Knock Knock Knocking on the Door
Oh Lord, Oh Lord
Oh Lord, Oh Lord
Oh Lord, Oh Lord
Oh Lord
Oh Lord, Oh Lord
Oh Lord, Oh Lord
Oh Lord
You're a hard one
You're a hard one to find
You're a hard one
You're a hard one to find
Knock Knock Knocking on the Door
Twice, Twice, Twice
Knock Knock Knocking on the Door
You keep me up at night
Oh Lord, Oh Lord
You keep me up at night
You're a hard one
You're a hard one to handle
Oh Lord, Oh Lord
I keep trying to figure you out
But you're a mystery
Knock Knock Knocking on the Door
Twice, Twice, Twice
Oh Lord, Oh Lord
Oh Lord, Oh Lord
Knock Knock Knocking on the Door
(You keep me up at night)
Knock Knock Knocking on the Door (Oh Lord)
(You keep me up at night)
Knock Knock Knocking on the Door (Oh Lord)
(Oh Lord)
(Oh Lord)
(Oh Lord)
(Oh Lord)
(Knock Knock Knocking on the Door)
