How come I always find Cleris songs when I look for Tuck Everlasting videos? :D This one's from that animated film, Fern Gully:
A Dream Worth Keeping
by Sheena Easton

Anytime you want to be right here
Just imagine me and all this will appear
You can keep this moment all your life forever near
A dream worth keeping

When you're feeling lost I'll be your star
Just reach out and touch me no matter where you are
In a world where precious things are disappearing over night
Just keep my star in site.

*I believe
We've found a dream that's worth keeping
For more than just a day
And even though
The winds of change may come sweeping
It's still a dream worth keeping
So don't let it fade away

Maybe you'll be in some distant land
Feeling all alone, but I'll be close at hand
And every time you see a rainbow paint the sky behind the rain
You'll be here again

*Repeat

Some day you might be thinking
That life has passed you by
Your spirits might be sinking
With hope in short supply
And that's the reason why...
That's the reason why....
I know this dreams worth keeping
For more than just a day
And even when you see the darkness come creeping
A dream worth keeping...

Can never fade away
