I was foolish - once
  And I let my "once" get away
  
  I was happy - once
  You'd never believe it today
  I got careless - once
  All at once you got away
  
  Life had beauty - once
  It's not worth livin' today
  I slipped out - once
  All at once you slipped away
  
  Oh great regret like the flavor of wine
  Only grows deeper with the passing of time
  
  Life had meaning - once
  It's cold and so empty today
  I was foolish - once
  I let my "once" get away
