Neil Young‘s 26th annual Bridge School Benefit concert went down over the weekend, with Jack White, Eddie Vedder, k.d. lang, the Flaming Lips and Gary Clark Jr. and more all joining forces to rock and roll and raise funds for children with speech and physical impairments. One of the more remarkable moments of the evening came when the notoriously tardy Axl Rose did what many thought he couldn’t and showed up on time and ready to rock, and Guns N’ Roses took to the stage for an all-acoustic (per Bridge School Benefit concert dictates) GNR set. The unlikely set spanned GNR’s career, including material from their 1987 debut Appetite for Destruction and 2008′s Chinese Democracy and everything in between, and was strewn with F-bombs, Rolling Stone reports. Charged rock classics like “Welcome To The Jungle” aren’t exactly meant to be played unplugged like this, but the boys did a good job turning the song into a real guitar jam, Rose seemed to be having fun and — most importantly! — a good cause was served. Pretty cool, eh?
