So yes, I have no life, so I had the interminable Live Earth coverage on the tube as I was cleaning my house on Saturday. And somewhere in the midst of all the nauseating celebrity preachiness, who should pop up playing with Madonna but Eugene Hutz and Sergey Rjabtzev of Gogol Bordello. Sure, I'd read last week that Madge was going to have them perform with her, but this is one of those have-to-see-it-to-believe-it, underground music rising up moments, like Modest Mouse on Saturday Night Live.
