The doctor who quote song

There are worlds out there where the sky is burning
Where the seas are asleep and the rivers dream
People made of smoke, and cities made of song
We've got work to do, come on!

The ground spins round at a thousand miles per hour
I can feel it as we fall through space
Around the sun we're hurtling
And to this world we cling

Have you ever wondered what it's like
To be wanderers in the fourth dimension?
There are lots of things to get across the universe
But most of all, you need a hand to hold

(I know what you're thinking
But what's the use of a good quotation if you can't change it?)

I'll be a story in your head that's okay
The daft old man who stole a magic box and ran away
A millennium in my time, but 50 years in yours
Since we first stepped through those police box doors

Courage is more than just not being frightened
Do what you're afraid of anyway, (Brave heart.)
I think it's fair to say in the language of your age
That I lived the dream, owned the stage. (Oh my giddy aunt!)
Machines make laws, but they cannot preserve justice
Only humans can do that
Love was never known for rationality
Geronimo! Allons-y! (Anyone for chess? Bring me knitting.)

Stars perish planets come and go
Matter disperses, coalesces, forms other patterns
Nothing is eternal I've seen universes
Freeze creations burn

I'll be a story in your head that's okay
The daft old man who stole a magic box and ran away
A millennium in my time, but 50 years in yours
Since we first stepped through those police box doors
