This was No.1 on this date in 1969.
And speaking of JoJo's former hometown. I lived there in the early 1980s. And I don't recall people being obsessed about this admittedly cool bit of trivia. Maybe they were when the song first came out. Or maybe trivia didn't really become a big thing until later.
Too bad “Washington” doesn't have four syllables. Perhaps the lads could have had JoJo flee the Inland Northwest. Though just imagine the lingering horror if they had mispronounced the name of a certain city.
