<div>
  <h2>AUBREY</h2>
  <p>And Aubrey was her name<br />
    A not so very ordinary girl or name<br />
    But who's to blame?<br />
    For a love that wouldn't bloom<br />
    For the hearts that never played in tune<br />
    Like a lovely melody that everyone can sing<br />
    Take away the words that rhyme, it doesn't mean a thing</p>
  <p>And Aubrey was her name<br />
    We tripped the light and danced together to the moon<br />
    But where was June?<br />
    No, it never came around<br />
    If it did it never made a sound<br />
    Maybe I was absent or was listening too fast<br />
    Catching all the words but then the meaning going past</p>
  <p>But God I miss the girl<br />
    And I'd go a thousand times around the world just to be<br />
    Closer to her than to me</p>
  <p>And Aubrey was her name<br />
    I never knew her but I loved her just the same<br />
    I loved her name<br />
    Wish that I had found the way<br />
    And the reasons that would make her stay<br />
    I have learned to lead a life apart from all the rest<br />
    If I can't have the one I want, I'll do without the best</p>
  <p>But how I miss the girl<br />
    And I'd go a million times around the world just to say<br />
    She had been mine for a day</p>
