[Stephen Hawking:]

For millions of years, mankind lived just like the animals

Then something happened which unleashed the power of our imagination

We learned to talk

[David Gilmour:]

There's a silence surrounding me

I can't seem to think straight

I'll sit in the corner and no one can bother me

I think I should speak now (Why won't you talk to me?)

I can't seem to speak now (You never talk to me)

My words won't come out right (What are you thinking?)

I feel like I'm drowning (What are you feeling?)

I'm feeling weak now (Why won't you talk to me?)

But I can't show my weakness (You never talk to me)

I sometimes wonder (What are you thinking?)

Where do we go from here (What are you feeling?)

[Stephen Hawking:]

It doesn't have to be like this

All we need to do is make sure we keep talking

[David Gilmour:]

(Why won't you talk to me?) I feel like I'm drowning

(You never talk to me) You know I can't breathe now

(What are you thinking?) We're going nowhere

(What are you feeling?) We're going nowhere

(Why won't you talk to me?)

(You never talk to me)

(What are you thinking?)

(Where do we go from here?)

[Stephen Hawking:]

It doesn't have to be like this
