Doctor Who: Rover by Jethro Tull

I chase your every footstep And I follow every whim. When you call the tune I m ready To strike up the battle hymn. My lady of the meadows My comber of the beach You ve thrown the stick for your dog s trick But it s floating out of reach. The long road is a rainbow and the pot of gold lies there. So slip the chain and I m off again You ll find me everywhere. I m a rover.
