Ah, here it is:

  COVENANT
  (Jan Harmon)
  
  
   1.         So .. what can we say that we haven't said before,
              standing here together?
              You .. like April knocking at my door
              in bright September's weather.
  
    Chorus:
              And I'll be near in the middle of the night,
              in case the moon awakes you.
              And I'll be near in the middle of the day,
              in case the sun forsakes you.
  
    2.         Who knows here we go from here?
              Who can see tomorrow?
              I'll tie my shoe while you straighten up your hair,
              and we'll walk through joy and sorrow. (cho.)
  
    3.        OH! How this place rings loud with love ...
              while dreams go spilling over!
              To think .. you've traveled all this way
              to be my friend and lover!  (cho.)
