Thousands of people came to San Francisco's Golden Gate Park Sunday to celebrate the 40th anniversary of the Summer of Love.
More than 100 artists, some whom were there the first time around, participated in a free concert Sunday to commemorate the year when San Francisco became the world's countercultural capital.
An estimated 50,000 people came together to celebrate peace, love and understanding, organizers said, despite the Labor Day weekend shutdown of the bridge connecting Oakland to San Francisco for repairs.
The nine-hour event began with blessings by Native American shamans and ended with Jolie Valente, son of the late Dino Valente of Quicksilver Messenger Service, singing his father's song "Get Together."
San Francisco police said the gathering proceeded harmoniously, with no major incidents reported.
"Just nothing but love," police Sgt. Mark Im said.
