Type 40 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
