During the "Summer of Love", psychedelic rock music was entering the mainstream, receiving more and more commercial radio airplay. The Scott McKenzie song "San Francisco (Be Sure to Wear Flowers in Your Hair)," written by John Phillips of The Mamas & the Papas, became a hit single in 1967. The Monterey Pop Festival in June further cemented the status of psychedelic music as a part of mainstream culture and elevated local Haight bands such as the Grateful Dead, Big Brother and the Holding Company and Jefferson Airplane to national stardom. A July 7, 1967, Time magazine cover story on "The Hippies: Philosophy of a Subculture," an August CBS News television report on "The Hippie Temptation" and other major media interest in the hippie subculture exposed the Haight-Ashbury district to enormous national attention and popularized the counterculture movement across the country and around the world.
The Summer of Love attracted a wide range of people of various ages: teenagers and college students drawn by their peers and the allure of joining a cultural utopia; middle-class vacationers; and even partying military personnel from bases within driving distance. The Haight-Ashbury could not accommodate this rapid influx of people, and the neighborhood scene quickly deteriorated. Overcrowding, homelessness, hunger, drug problems, and crime afflicted the neighborhood. Many people simply left in the fall to resume their college studies. On October 6, 1967, those remaining in the Haight staged a mock funeral, "The Death of the Hippie" ceremony, to signal the end of the played-out scene. Mary Kasper explained the message of the mock funeral as follows:
We wanted to signal that this was the end of it, don't come out. Stay where you are! Bring the revolution to where you live. Don't come here because it's over and done with.
