When Late Night with Conan O'Brien debuted 15 years ago (!) Radiohead was the show's first musical guest. These days, both are huge names in their respective fields and quite eco-friendly, so O'Brien had the band back for his "green" Earth Day show. The band performs In Rainbows' "House of Cards" from a London soundstage, especially for the show. (There's of course a Kyoto conference-related jab at US president George W. Bush. Surprise.)
