From Australian website Tone Deaf, one of Australia’s leading authorities on local and international music, culture, and industry:
Pearl Jam’s fourth drummer, Jack Irons, joined Eddie Vedder on stage in Seattle to perform Pink Floyd’s “Shine On You Crazy Diamond” on March 17, and video from the performance has hit the net.
Irons drummed on Pearl Jam’s 1996 album No Code, and 1998’s Yield, before leaving, citing a heavy touring schedule as his reason.
Interestingly, Irons was the founding drummer for Red Hot Chili Peppers, and was actually asked to join Pearl Jam in 1990, instead passing his copy of their demo onto a young singer he knew, named Eddie Vedder.
And from Rolling Stone Magazine: “Vedder and Irons’ reunion came just a week after Pearl Jam invited all five of their drummers – Irons, Dave Krusen, Dave Abbruzzese, Matt Chamberlain and current drummer Matt Cameron – to their Rock and Roll Hall of Fame induction ceremony in April; only Krusen and Cameron will be inducted. Irons is already a member of the Rock Hall thanks to his induction alongside Red Hot Chili Peppers.”
