Neil Young saw the pictures of the incident in Life Magazine and wrote this song. Released in June 1970, the song was a top 20 hit - despite being banned on many radio stations for its indictment of the Nixon administration - and a poignant reminder of what had happened on that fateful day.
The incident and the song sped the tide of sentiment already turning against the US involvement in Vietnam. The massacre in Ohio is one of the darkest moments in American history, and this song brilliantly captures the nation's feelings. Music can really capture and sway a culture, and this song is perhaps the best example of that.
Here's Young performing his song solo.
