Well, who-who, who's that knocking?
Who-who, who's that knocking?
Who-who, who's that knocking, baby?
Who-who, who's that knocking?
Who's that knocking, knocking at my front door?

Well, it must be my baby
That I long to see
'Cause it gets so doggone lonesome
When she is not with me
Who's that knocking, knocking at my front door?

Well, I keep that candle burning
Burning night and day
So my baby can see the light
When she comes my way
Who's that knocking, knocking at my front door?

Well-well, who-who, who's that knocking?
Who-who, who's that knocking?
Who-who, who's that knocking, baby?
Who-who, who's that knocking?
Who's that knocking, knocking at my front door?
(Let's knock it one time!)

Well, come on in sweet baby
Nobody here but me
Come on in sweet baby-baby
And keep me company
Who's that knocking, knocking at my front door?

Well, who-who, who's that knocking?
Who-who, who's that knocking?
Who-who, who's that knocking, baby?
Who-who, who's that knocking?
Who's that knocking, knocking at my front door?
(Knock it again!)

Well, who-who, who's that knocking?
Who-who, who's that knocking?
Who-who, who's that knocking, baby?
Who-who, who's that knocking?
Who's that knocking, knocking at my front door?

Covered by UK's Whirlwind on their first LP in 1977, the title was changed to "Who's That Knocking?" to avoid a mix-up with the Darts' cover of the doo-wop song "Who's That Knocking?" originally by The Genies (SHAD 5002, 1959).
