Verse 2 - same chords as Verse 1 -:
The doctor isn't here this time this wont be a breeze
He's stuck in 1969 on your DVDs
Just listen very carefully to what he's got to say
Do not turn your back on them and don't look away

If they get inside the Tardis then the sun will go out
Just go down to the cellar and show them what you're about
They move faster than you could ever believe
Don't let the light go out and don't be naive

So don't blink,

I said, don't blink

My eyes are watering, I'm right on the brink
    Gb                       Db
I'm sure nothing would happen if I were to-

The future's coming quickly so please don't be scared
    Gb                              Db
The answers will find you just make sure you're prepared
B                                   Ab
When you see the Doctor then you'll work out the link
    Gb                               Db
But even though its ended please be sure not to blink
