I know this mad excitement:
Isn't it fine to know
That love is real
In what we feel
And all we have to show.
In all this gay confusion,
It's a comfort just to see,
That what you say,
Is what you mean,
The words are meant for me.

Let people say just what they will;
As time goes by, I love you still.
You are my love.
They think they know us, but they don't.
They never will, I know they won't,
They never will.

You know, I tell you so.
I know, 'cause you tell me.
You know 'cause I tell you so
And I know, you tell me.

Every day I see your face
Makes this world a better place for me to be,
A better place for me to be.
And every time I touch your hand,
Troubles fade like grains of sand, beautiful away.

People say just what they will;
As time goes by, I love you still.
You are my love.
They think they know us, but they don't.
They never will, I know they won't,
They never will
And I don't care.

You know, 'cause I tell you so.
I know, 'cause you tell me.
You know 'cause I tell you so
And I know, 'cause you tell me.

You know, 'cause I tell you.
I know, 'cause you tell me.
You know;
I know 'cause you tell me,
It's true.

In a German interview from the period, John simply characterised this song as a "merry love song".
