Thanks for all your replies, everyone.
I did a quick search on amazon and found a DVD of the festival, but it's a box set with Hendrix and Redding complete sets added. Anybody know if there's just a DVD release of the original festival? I mean, Otis and Jimi are great and all, but I'm not a particularly rabid fan (I get most of my R&B via Motown, and I was never into the whole guitar-god thing) and it's like, 60 big ones for the box set.
