Ray Charles recorded this song, written by M. Parish and H. Roemheld, titled "Ruby". I thought it was a poignant love song until I was told that Ruby was a metaphor for heroin. That concept is consistent with the lyrics. Does anyone have any additional or corroborating information on this?

  They say, Ruby you're like a dream,
  Not always what you seem

  And though my heart may break
  When I awake
  Let it be so, I only know,
  Ruby it's you
  
  They say, Ruby you're like a song,
  You just don't know right from wrong
  And in your eyes I see
  Heartache for me
  Right from the start, who stole my heart
  Ruby it's you
  
  I hear your voice, and I must come to you
  I have no choice, what else can I do?
  
  They say, Ruby you're like a flame,
  Into my life you came
  And though I should beware
  Still I don't care
  You thrill me so, I only know,
  Ruby it's you

Thanks, Gary
