The four surviving core members of the Grateful Dead performed at San Francisco’s AT&T Park as part of the Giants’ Jerry Garcia Tribute Night yesterday. The Ben & Jerry’s-sponsored event marked the 15th anniversary of the Grateful Dead guitarist’s passing. The night opened with a performance by the Dead cover band Cryptical at home plate and boasted a rendition of the National Anthem by Bob Weir, Phil Lesh and their Furthur backup singer Jeff Pehrson.

In addition, the guitarist’s daughter Annabelle Garcia spoke about her father and longtime Deadhead Bill Walton spoke about the band. During the game’s seventh-inning stretch, Walton, Mickey Hart and Bill Kreutzmann made an unsuccessful attempt to set a world record for being the largest kazoo ensemble to the tune of “Take Me Out to the Ball Game.” The game marked the first time the four members of the Grateful Dead have performed at the same event on the same day since Rothbury 2009, though Dead offshoots Furthur and Rhythm Devil performed at Bridgeport, CT’s Gathering of the Vibes on different days.
