Lyrics:

Those schoolgirl days
Of telling tales and
Biting nails are gone

But in my mind, I know
They will still live on and on

But how do you thank someone
Who has taken you from crayons to perfume
It isn't easy but I'll try

If you wanted the sky
I would write across
The sky in letters
That would soar
A thousand feet high
To Sir with love
The time has come
For closing books and
Long last looks must end

And as I leave, I know that
I am leaving my best friend

A friend who taught me right from wrong
And weak from strong
That's a lot to learn
What, what can I give you in return?

If you wanted the moon
I would try to make a start
But I would rather you
Let me give my heart
To Sir with love
