Buffalo Springfield performs at the famous 1967 festival. Neil Young did not attend, but David Crosby filled in. Peter Tork provided the introduction.
You may never be able to take this song seriously again.
The surviving members of the band (Young, Stills, and Furay) performed together for the first time since 1968 at the Bridge School Benefit in Mountain View, CA, which raises money for severely disabled students. It's a concert that Young and his wife have been putting on for years. The camera in this video is shaky, but the audio is great.
Just one example of the many ways in which this song has infiltrated popular culture.
