Lyrics:

[TT:] Ooh here I am alone, thinkin' aimlessly
Seein' other girls in love and wishin' 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

[Both:] When love comes knockin' at my heart
I'm surely gonna let it in
When love comes knockin' at my heart
Happiness will surely begin
[TT:] Oh darlin', [MG:] Oh darlin'
[TT:] Oh darlin', [MG:] Oh darlin'

[MG:] Emptiness is in the air and all around me gloom
As I gaze through the window of my lonely room
I hate to get up in the mornin' 'cause I know what lies ahead
Where there should be a cheerful smile, there's loneliness instead

[Both:] When love comes knockin' at my heart
I'm surely gonna let it in
When love comes knockin' at my heart
Happiness will surely begin

[MG:] Oh if you've never been in love, darlin'
Then you're just like me, now
[TT:] Don't you get lonely? What am I to be?
Oh darlin', [MG:] Oh darlin'
[TT:] Oh darlin', [MG:] Oh darlin'
[TT:] Oh darlin', [MG:] Oh darlin'
[TT:] Oh darlin', [MG:] Oh darlin'

[TT:] My heart's full of envy for the girl who lives next door
She has so many things that I've never had before
[MG:] She possesses one thing I've never had a chance to get
That's someone to call her own and there's one thing you can bet

[Both:] When love comes knockin' at my heart
I'm surely gonna let it in
When love comes knockin' at my heart
Happiness will surely begin
[TT:] Oh darlin', [MG:] Oh darlin'
[TT:] Oh darlin', [MG:] Oh darlin'

[TT:] 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 darlin', when love comes
