Last night, Conan had Pearl Jam on as his first musical guest since taking over the Tonight Show. Last night he had Green Day on to perform "Know Your Enemy" a song that is as political as it is catchy. Which is to say, it's not political (it is if your political knowledge peaked at 13) or catchy. This marks the second mainstream rock act Conan has had on, and I'm hoping he doesn't end up abandoning the indie rockers he used to have on when he was in New York.
