Pearl Jam turned their New York concert on Wednesday night (25Jun08) into a star-studded affair when they welcomed former Kiss star Ace Frehley and Ramones bassist C.J. RAMONE onstage.
Ramone was a special guest at Tuesday's (24Jun08) Madison Square Garden show, and he showed up for a second night.
But it was Frehley who wowed the crowd - he teamed up with Eddie Vedder and his band on a cover of Kiss' Black Diamond, which featured drummer Matt Cameron and guitarist Mike MCCready on lead vocals.
Ramone performed a rendition of punk anthem I Believe in Miracles with Pearl Jam - as he had the night before.
And the stars weren't only spotted onstage - the Olsen Twins, Coldplay frontman Chris Martin and Tim Robbins and Susan Sarandon were among the fans who caught the two New York shows.
