Hi Joe

v1 - Father is correct.

v3 I give in full, there are a few changes:

  In the good old steamboat days,
  Five towns 'd meet your gaze,
  Saint Louis, she was one, you know;
  And New Orleans was far from slow
  And dear old Memphis, too,
  Well, she was at quite a few
  But goodness how they've growen since
  The good old steamboat days,
  Since the good old steamboat days.

v4 - It sounds to me like:
  Fish call pikes and cats

v5 - a couple of minor changes:
  For the captain held a gun.
  Then coroner held an inquest
