Lời bài hát: Olivia Newton-John. The Key.

There's a key to open every heart
You must play your part
To open the door
There's a dream for each to be fulfilled
A yearning to be stilled
You can't ask for more

Don't get down
Don't get disheartened
There's someone who
Is waiting there for you

On your own is the loneliest place to be
We all need love, can't you see
And they need you
How they need you

Oh, don't get down
Don't get disheartened
There's someone who
Is waiting there for you

On your own is the loneliest place you can be
We all need love, can't you see
And they need you
Yes, they need you
Oh, they need you
Oh
We all need love, can't you see
And they need you
Yes, they need you
How they need you
You're the key
