I always thought that was the name of the song! (Spoiler alert: I was wrong.) The Buffalo Springfield classic that begins with those two haunting chords. It wasn't about anti-war protests. At least (in the wake of the death of the author) you can make it about that if you will. The catalyst for the creation of the song was the Sunset Strip curfew in Los Angeles in late 1966. It has taken me sixty years to learn this. Who knows how much learning is ahead for me? For what it's worth.
