Mr. Soul Buffalo Springfield= Stephen Stills, Neil Young, Dewey Martin, Bruce Palmer, Richie Furay

"Mr. Soul" is about Neil Young's personal problems with fame and disregard towards rock stardom. It was written by Young after experiencing an epilepsy attack after an early show with Buffalo Springfield in San Francisco. Many people in the audience were questioning if it was part of the act. While being a patient at UCLA Medical Center's neuropsychiatry branch, he wrote the song once he was awake and recovering and told to return for further tests. The lyrics had reflected Young's experience, feeling as though he was about to die. Thereupon, he was advised by his doctor to never take LSD or any other hallucinogenic drugs.
