By the 1970s, the 1960s zeitgeist that had spawned hippie culture seemed to be on the wane. The events at Altamont Free Concert shocked many Americans, including those who had strongly identified with hippie culture. Another shock came in the form of the Sharon Tate and Leno and Rosemary LaBianca murders committed in August 1969 by Charles Manson and his "family" of followers. Nevertheless, the turbulent political atmosphere that featured the bombing of Cambodia and shootings by National Guardsmen at Jackson State University and Kent State University still brought people together. These shootings inspired the May 1970 song by Quicksilver Messenger Service "What About Me?", where they sang, "You keep adding to my numbers as you shoot my people down", as well as Neil Young's "Ohio", a song that protested the Kent State massacre, recorded by Crosby, Stills, Nash and Young.
