Lyrics:

A man is in love,
How did I know?
He came walking with me
And told me so,
In a song that he sang
And then I knew,
A man is in love
With you.

A man is in love,
How did I hear?
I heard him talk too much
When you are near,
He whispered your name
When his eyes were closed,
A man is in love
And he knows.

A man is in love,
How did I guess?
I figured it out while he was
Watching your dress,
He'd give you his all
If you'd but agree,
A man is in love,
And he's me.
