Anyone know when/where this photo might have been taken? I've seen Jerry play a Les Paul Junior before. And it looks like they're using Kustom amps, which I've never seen The Dead use before. I always had the impression their late 60's backline was all Fender. And it looks like Pigpen is also playing a Kustom organ, which I've never seen before, as well. Didn't Pig usually use a Vox Continental or Hammond B-3?
