  • Have you and her been taking pictures of your obsessions?

    Because I met a boy who went through one of your sessions

    In his blue velour and silk

    You liberated

    A boy I never rated

    And now he's throwing discus

    For Liverpool and Widnes

    You liberated

    A boy I never rated

    And now he's doing business
