Eddie Vedder

The war of words continues.

Nikki Sixx blasted "boring" Pearl Jam in response.

Foo Fighters and Jackson Browne also booked for event, marking what would have been late rocker's 70th birthday.

Pearl Jam frontman Eddie Vedder made a surprise appearance at the Oscars ceremony last night.

Roger Waters was performing in Chicago at the United Center when Eddie Vedder jumped on stage to help him with 'Comfortably Numb' and it was EPIC.
