Conan takes over for Jay Leno on June 1, and he is set to hit the ground running in the musical guest department, as Pearl Jam have been scheduled to appear on Conan's premiere episode. Pearl Jam are reportedly working on a new album, but what they'll be playing is up in the air.

Will Ferrell will be Conan's first non-musical guest, and he'll be promoting Land of the Lost. The show premieres on June 1 at 11:35 p.m. EST.
