First Guests Announced for the Premiere of The Tonight Show with Conan O'Brien

NBC has made Entertainment Blogger a happy camper today (which negates his unhappiness over rival network ABC cancelling Samantha Who?). Why? Because his favorite band was announced as Conan O'Brien's first musical guest when he takes over the reins of The Tonight Show from Jay Leno! NBC announced today that Pearl Jam and Land of the Lost star Will Ferrell will appear on O'Brien's debut show, scheduled for June 1.
