[Verse 1]
Hoo, here I am alone, thinking aimlessly
Seeing other girls in love and wishing it were me
If I could only find the key and make love come my way
I would trade this loneliness for true love any day

[Chorus]
When love comes knocking at my heart
I'm surely gonna let it in
When love comes knocking at my heart
Happiness will surely begin
Oh darling, oh darling

[Verse 2]
Emptiness is in the air, all around me gloom
As I gaze through the window of my lonely room
I hate to get up in the morning
'Cause I know what liеs ahead
Where thеre should be a cheerful smile
There's loneliness instead

[Chorus]
When love comes knocking at my heart
I'm surely gonna let it in
When love comes knocking at my heart
Happiness will surely begin
[Bridge]
If you've never been in love
You are just like me, oh baby
Don't you get lonely? What a life to lead, woo
Oh darling, whoa-ho, oh darling
Oh darling, whoa, whoa, darling

[Verse 3]
My heart's full of envy
For the girl who lives next door
She has so many things that I've never had before
She possesses one thing I've never a chance to get
And that's someone to call my own
But there's one thing you can bet

[Chorus]
When love comes knocking at my heart
I'm surely gonna let it in
When love comes knocking at my heart
Happiness will surely begin
Oh darling, oh darling

[Outro]
When love comes, I'm gonna let it in
Because I know I'll be happy then
Loneliness will be no more
When love comes, gonna open that door
When love comes, when love comes
Oh darling, when love comes
Gonna let it in, whoa-oh, darling
When love comes, I'm gonna let it in
Because I know I'll be happy then
