Clarification on Conan O’Brien Appearance

We reported earlier that Radiohead will be musical guests on Late Night with Conan O’Brien on October 18. Many of you have pointed out that October 18th is a Saturday and Conan does not air on Saturday nights. Our information was a little confusing so please accept our apologies.
We are under the impression that Radiohead will be guests on the Conan O’Brien show on Friday, October 17th with actor John Cusack and actress Gina Gershon also appearing. The episode will repeat on Comedy Central October 20 at 6pm ET and again on October 21 at 12pm ET.
It has also been rumored that Radiohead will appear on the Late Show with David Letterman the same night.
Both appearances are rumors at this point so once we have some solid info, we’ll pass it along.
UPDATE: Radiohead has been taken off the upcoming Conan O’Brien schedule so they will NOT be performing on the show. It looks as if they will be doing the Late Show with David Letterman on October 17th instead. We’re still waiting confirmation.
UPDATE #2: To confirm- Radiohead will be doing Letterman on the 17th (Friday night), and will not be doing Conan O’Brien.
