There's a "math errors" thread, let's have one for the social sciences. (A search for thread titles with "historical" didn't show a thread like this one. Apologies if I missed a synonym.) A couple of examples for starters. U2, "Pride (In the Name of Love)." Bono sings "early morning, April fourth" while recounting a tragic event that actually occurred in the early evening. "Rip Van Ruben," a demo recorded by Andy Partridge as a candidate for the Nonsuch album. The lyric "Dream you're Frank L. Richards and this is the great land of Oz" arose from Andy's misremembering the name of author L. Frank Baum, as he has subsequently recalled with some embarrassment.
