Here’s an article by writer Isaac Asimov about the origins of “The Star Spangled Banner.” It first appeared (I think) in ISAAC ASIMOV’S SCIENCE FICTION MAGAZINE in the early ’90s. I was a subscriber at the time, but didn’t actually read the article until a couple of years later. I was so impressed that I photocopied it (in violation of the law) and passed it around at work. Someone on Stg. Stryker’s Daily Briefing mentioned verse 4 and reminded me that I had wanted to find this article and post it. Check it out.
