What would Pearl Jam Week be without Pearl Jam? Last night on Jimmy Fallon Pearl Jam took the stage to perform Sirens. It's also worth mentioning that Pearl Jam interviewer extraordinaire, Judd Apatow was a guest on the show. Tonight, the last night of Pearl Jam Week, Pearl Jam will, through the magic of TV, take the stage one more time during or shortly after their show in Hartford. Lightning Bolt is the likely (though not confirmed) track.
