Powered by the eye of harmony
I can travel anywhere in space and time
I'm linked to the Doctor symbiotically
Got his imprint on my briode nebuliser

There used to be 305 of me
But the rest were decommissioned and replaced
Takes 6 pilots to fly me properly
Only happened once at the Medusa Cascade

The last Type 40 in the universe, but there's still so much to see
But I'll be going on adventures so long as there's huon energy
My chameleon circuit hasn't worked since 1963
But the Doctor won't give up on me

My interior's in a state of temporal grace
Though on occasion that gets circumvented
Inside me there's an awful lot of space
Because I'm dimensionally transcendental

I've withstood falling down for miles and miles
Suffered three thousand degree heat without scorching
Hit by the Titanic when I was in mid-flight
Every time he's sure to fix me
