It's a rare occurrence for Radiohead to make an appearance on American television. It's also rare for The Colbert Report to run for an hour and focus on just one guest. Which is why Sept. 26 will be like Haley's Comet, a lunar eclipse, and a new Scott Walker album all rolled into one: Radiohead will appear on a special hour-long Colbert Report and perform four songs from this year's The King Of Limbs and a new song, "The Daily Mail." Colbert says he plans on "leveraging their anti-corporate indie cred to raise brand awareness for my sponsors.” We're laughing already!
