The "Los Angeles Times" reported that as many as 1,000 youthful demonstrators, including such celebrities as Jack Nicholson and Peter Fonda (who was afterward handcuffed by police), erupted in protest against the perceived repressive enforcement of these recently invoked curfew laws. This incident provided the basis for the 1967 low-budget teen exploitation film "Riot on Sunset Strip", and inspired multiple songs including the famous Buffalo Springfield song "For What It's Worth". On January 14, 1967, the outdoor Human Be-In organized by Michael Bowen helped to popularize hippie culture across the United States, with 20,000 hippies gathering in San Francisco's Golden Gate Park. On March 26, Lou Reed, Edie Sedgwick and 10,000 hippies came together in Manhattan for the Central Park Be-In on Easter Sunday. The Monterey Pop Festival from June 16 to June 18 introduced the rock music of the counterculture to a wide audience and marked the start of the "Summer of Love". Scott McKenzie's rendition of John Phillips' song, "San Francisco", became a hit in the United States and Europe. The lyrics, "If you're going to San Francisco, be sure to wear some flowers in your hair", inspired thousands of young people from all over the world to travel to San Francisco, sometimes wearing flowers in their hair and distributing flowers to passersby, earning them the name, "Flower Children". Bands like the Grateful Dead, Big Brother and the Holding Company (with Janis Joplin), and Jefferson Airplane lived in the Haight. In June 1967, Herb Caen was approached by "a distinguished magazine" to write about why hippies were attracted to San Francisco. He declined the assignment but interviewed hippies in the Haight for his own newspaper column in the "San Francisco Chronicle". Caen determined that, "Except in their music, they couldn't care less about the approval of the straight world." Caen himself felt that the city of San Francisco was so straight that it provided a visible contrast with hippie culture. On July 7, "Time" magazine featured a cover story entitled, "The Hippies: The Philosophy of a Subculture." The article described the guidelines of the hippie code: "Do your own thing, wherever you have to do it and whenever you want. Drop out. Leave society as you have known it. Leave it utterly. Blow the mind of every straight person you can reach. Turn them on, if not to drugs, then to beauty, love, honesty, fun."
