The Chemical Brothers on the main stage a few years were fantastic and the crowd were really up for it until some killjoy from the health and safety turned down the music, best lightshow as well, they were really going for it before that and the crowd were going mental, but i have to say Underworld on the main stage beat them for buzz and atmosphere, i reckon 90% of the crowd were on something and when 'King of Snake' and 'Born Slippy' were played it was one of my best Glastonbury moments.
