Thanks for the link to that video, it was really cool!
To see a high quality clip from that era is always a treat ... '72 must have been a special year in a lot of ways, at least by the way their sound was starting to evolve into a more polished feel. Yeah, that boxed set does look pretty nice, I guess they were all snatched up pretty quick. Why the limited release, I kind of don't get that? I understand the business logic, but why turn it into a collector's item? Unless they figure it'll be a thing of diminishing returns as illegal copies start to circulate over time. Update: just read the page you linked to, I guess they're still selling the full series, but not as a limited edition boxed set (7,200 copies) . The funny thing is that it looks like you still have to buy the full series -- it's just not packaged as a "boxed set". Personally, I would rather spend the 450 beans on seeing furthur now, live ... while they're still here with us.
But yeah, the internet has actually helped circulate non-official footage and such. Too bad I'm an satellite ISP with a bandwidth quota though.
