Ben sat in with Pearl Jam for "Indifference."
Amazing intimate gig topped by the appearance of Ben for the finale (we were expecting it since he was playing Lolla the next day, but still :)).
I'd been waiting so long to see Ben and PJ on the same stage, I almost cried..ended up happening 3 times over the weekend!
there's an official photo of Ben on the PJ website: www.pearljam.com/i/tourphotos/20070802/7.jpg
audience recordings exist, out there soon hopefully
