It's been such a long time since I met you back on Skaro
And I'm pretty sure that you know
That not much has changed since then
It doesn't matter how hard you try to remove me
I think you will agree
That if one of us dies, then the other will too
I am locked in war with you
Exterminate, Regenerate
I thought you always knew our fate
To just keep fighting on and on
While time keeps turning
Regenerate, Exterminate
And even though we are the same
Why don't you hop into your ship
And leave me burning
Even though, as men, we have our contrasts
We're of exactly the same class
And our constant companion is death
