I´ve listened to the Gordon Lightfoot song many times over the years enough to know a little about this. Do you have any personal memories from when it happened?
According to the twitterverse Gordon Lightfoot no longer sings, "a main hatchway caved in" after forensic evidence indicated otherwise.
That is true. He now sings, "At 7 p.m. it grew dark, it was then he said..."
There is a list of inaccuracies in the "Artistic License" section of the song's Wikipedia entry. In a couple of cases, he has changed what he sings in live performances, e.g. it is now a "rustic old hall", not a "musty old hall".
Maybe I´ll have to dig out my old vinyl album (from 1976) and relisten to the song and check for inaccuracies. Where do I go to get an updated version if necessary?
I'm not sure Lightfoot recorded the updated version but he has changed some lyrics in live performances. He has also retained some inaccuracies because they fit the rhyme and rhythm better, e.g. in real life, "they left fully loaded for" Detroit, not Cleveland.
It turns out there is a whole genre of Disaster Songs in Canada!
I forgot to answer Bubo's question about personal memories. No, I don't remember hearing about the Edmund Fitzgerald before the song came out. I *do* remember the first Prime Minister Trudeau though!
And I remember when the current Prime Minister Trudeau was born on Christmas Day. It was a big deal!
