Legendary ’60s group Buffalo Springfield reunited this past weekend at Mountain View, CA’s Shoreline Amphitheatre as part of Neil Young’s Bridge School Benefit. Classic Buffalo Springfield members Young, Stephen Stills and Richie Furay performed at the charity concert on both Saturday and Sunday. It was the first time since 1968 that the three musicians have shared the stage. The benefit also featured marquee performances by Pearl Jam, Elvis Costello, Lucinda Williams, Billy Idol, Jackson Browne and David Lindley, Modest Mouse and Grizzly Bear, among others.

The Buffalo Springfield members offered a single set each day that included such songs as “On The Way Home,” “Rock & Roll Woman,” “A Child’s Claim To Fame,” “Do I Have To Come Right Out And Say It?,” “Go And Say Goodbye,” “I Am A Child,” “Kind Woman,” “Burned,” “For What It’s Worth,” “Nowadays Clancy Can’t Even Sing,” “Bluebird” and “Mr. Soul.” Crosby, Stills & Nash drummer Joe Vitale performed in place of Buffalo Springfield drummer Dewey Martin (who died of natural causes in 2009), while Young collaborator Rick Rosas sat in for founding bassist Bruce Palmer (who died of a heart attack in 2004). Jim Messina, who replaced Palmer on the band’s final album, did not appear at the reunion.

Neil Young performed at various other times throughout the two-day event. Both days he offered versions of his own “Sugar Mountain” and “Comes A Time.” In addition, he sat in with Leon Russell & Elton John for “Gone To Shiloh” and joined Pearl Jam for “Walk With Me,” the latter of which appears on his new studio album Le Noise. Pearl Jam’s sets doubled as the alt-rock icon’s 20th anniversary shows (the band played its first show on October 22, 1990). The group shuffled its setlists between shows, performing hits like “Daughter” and “Black” one night and Wayne Cochran’s “Last Kiss,” “Nothingman” and “Better Man” the next. The band also covered Patti Smith’s “Dancing Barefoot” and debuted a live version of its B-Side “Other Side,” among other songs.

Several other collaborations marked the two-day show. Emmylou Harris made a surprise appearance with Lucians Williams on “Greenville,” Pegi Young and Williams sat in with Elvis Costello on “Scarlet Tide” and most of the evening’s performers—including Eddie Vedder and Jackson Browne—joined Young for a show-closing take on “Rockin’ In The Free World.”
