I've caught them quite a few times and the No Quarter cover is amazing. Their Neil Young covers are also special. The Southern Man w/ Chris Robinson in Atlanta a few years ago was one of the best moments I've seen live. Then Greg Allman came out and it was just fantastic. This past summer at Bonnaroo was probably the best though. To end the first set: Moby Dick Reprise with John Paul Jones on Bass Livin' Lovin' Maid with John Paul Jones on Bass Since I've Been Lovin You with John Paul Jones on Keys No Quarter with John Paul Jones on Keys The encore was: 8. Sweetleaf> 9. War Pigs Unreal. Warren is definitely one of the most enjoyable guitarist I've ever heard. Mule rocks!
