Powered by the eye of harmonynI can travel anywhere in space and timenI’m linked to the Doctor symbioticallynGot his imprint on my briode nebulisernnThere used to be 305 of menBut the rest were decommissioned and replacednTakes 6 pilots to fly me properlynOnly happened once at the Medusa CascadennThe last Type 40 in the universe, but there’s still so much to seenBut I’ll be going on adventures so long as there’s huon energynMy chameleon circuit hasn’t worked since 1963nBut the Doctor won’t give up on mennMy interior’s in a state of temporal gracenThough on occasion that gets circumventednInside me there’s an awful lot of spacenBecause I’m dimensionally transcendentalnnI’ve withstood falling down for miles and milesnSuffered three thousand degree heat without scorchingnHit by the Titanic when I was in mid-flightnEvery time he’s sure to fix me
