After the January 14, 1967 Human Be-In in San Francisco organized by artist Michael Bowen, the media's attention on culture was fully activated. In 1967, Scott McKenzie's rendition of the song "San Francisco (Be Sure to Wear Flowers in Your Hair)" brought as many as 100,000 young people from all over the world to celebrate San Francisco's "Summer of Love." While the song had originally been written by John Phillips of The Mamas & the Papas to promote the June 1967 Monterey Pop Festival, it became an instant hit worldwide (#4 in the United States, #1 in Europe) and quickly transcended its original purpose.
