Notes
Ohio, especially the live version on 4 Way Street, is one of the most powerful anthems of young people standing up to the government and saying "what you did was wrong". The song describes the killings of 4 students at Kent State University in 1970. The power of the song is really driven home by David Crosby's cries at the end of the song -- "How many more!".
Whenever the government or law enforcement oversteps its bounds, there should be a song like "Ohio" to make the statement that this is not ok.
