モントレー・ポップ・フェスティバル
Following its appearance on the band's second album, the song would go on to become a staple of the Byrds' live concert repertoire, until their disbandment in 1973. The band also performed the song during their appearance at the Monterey Pop Festival on June 17, 1967, where band member David Crosby made controversial remarks alleging that Kennedy had not been killed by Lee Harvey Oswald alone, but was shot from multiple directions. The Byrds' performance of "He Was a Friend of Mine" at Monterey was included in the 2002 "The Complete Monterey Pop Festival" DVD box set.
