Gaslight Anthem have confirmed that they will be appearing on Late Night with Conan O'Brien on December 9th. The band explained:

So we just got confirmed to perform on Late Night with Conan O'Brien…it's pretty crazy, to be honest, but heck, we're definitely psyched. We'll be on Tuesday December 9th. So tune if you can, even if it means messing with your TV's rabbit ears, or setting up TiVO, or whatever.

The band continues to support their SideOneDummy debut, The '59 Sound.
