Bonnaroo 2007, Day Two: Ben Harper, Roots, Led Zeppelin SuperJam! Plus: Lily Allen on Xanax

What a crazy day at Bonnaroo. Though Friday was Day Two at the Tennessee festival, it marked the moment when Bonnaroo officially went off the hook. Lily Allen popped a Xanax (before her set) and drank half a bottle of Jagermeister (during her set) but neither pharmaceuticals nor excess quantity of alcohol could deter her from delivering one of the days hottest performances. (We caught up with her back at her bus, where Allen celebrated by plowing into a bag of Nacho Cheesier Doritos.) Elsewhere, Cold War Kids frontman Nathan Willett described to us how the kids at the 'Roo lose their minds, and the Roots covered "Roxanne" in anticipation of the Police's Saturday gig. Tool closed the main stage, unveiling an insane laser show, but the highlight of the day (in fact, it was the wee hours of Saturday morning) was the annual SuperJam, which this year featured Ben Harper, Led Zep bassist John Paul Jones and Roots drummer ?uestlove, who smoked out snippets of Zep classics like "Immigrant Song," "When the Levee Breaks" and "Good Times, Bad Times." Check out the highlights, and stay tuned to RollingStone.com for updates all weekend.
