A lot of celebratory joints will be lit this weekend as Deadheads everywhere rejoice in the news that the seminal jam band the Grateful Dead is reuniting for a tour. The band's four surviving members, Mickey Hart, Phil Lesh, Bob Weir, and Bill Kreutzmann, will tour for the first time since 2004 this April and May. Obama inspired the reunion: The Dead began to smooth over years of infighting after performing at an Obama fundraiser in October. "It broke the ice," drummer Mickey Hart told Rolling Stone. "We were able to let some of these skeletons in our closet just fall away." Of course, the Dead will be without Jerry Garcia, the band's leader, who died in 1995, making this reunion tour a bit like The Pips without Gladys Knight, the Family Stone without Sly, and the Experience without Jimi Hendrix.
