Yes!

  When suppertime came, the old cook came on deck sayin'
  "Fellas, it's too rough to feed ya"
  At seven PM, a main hatchway caved in, he said
  "Fellas, it's been good to know ya"

That's the lyric Lightfoot changed when sung live, to take into account the more recent hypothesis on how it sank:

    At seven p.m. it grew dark; it was then

Which is nicer to the crew (doesn't imply it was a mistake on their part) but doesn't really quite flow as nicely.
