The tragedy happened in November of '75, and looking online, it says the song was released in August of '76. 9 months doesn't seem out of line to me?The Wreck of the Edmund Fitzgerald came out mere months after the ship went down. I was in Minnesota with my grandparents on vacation the Summer after the sinking occurred, and a couple of my cousins knew one of the crew. The song really hit them hard. They both thought the release of the song was too soon after the tragedy, though their tone softened up a bit as time went on.
