The summer of 1967 forever changed American culture. It was a summer of anti-war protests, peace movements, love, flowers, drugs and rock and roll. It became known as the “Summer of Love.” Scott McKenzie sang what would become one of the summer’s theme songs: “If you’re going to San Francisco, be sure to wear some flowers in your hair” Fifty years ago, thousands of people gathered in San Francisco, California. They heard new music by groups that went on to write songs that are still famous today.
