A fan's appetite is insatiable as we know, however, as a fan who understands what Michael was going through on that day and in that footage - I totally understand why he said it shouldn't be released.
I have seen this footage but (because I asked politely to be shown it). There were also many fans at the rehearsal! There are many people who went to the shows. Those people are not usually on the Michael Jackson fan forums (anymore, anyway!)
So, ask somebody that was there or ask somebody that filmed it to show it to you in the flesh. If you want to see any footage uploaded you can also ask the estate - I am sure one day, if they see fit, they'll release it.
Anthony isn't going to release anything, these videos are just a commentary for people who might be interested in that kind of thing, nothing else. You have to speak to other people if you want footage released. There are quite a few people who do have a lot of rare footage - but it is not their right to release it or leak it - why would anyone do that anyway? It's illegal and disrespectful.
However, I do own This is it on Blu ray, if anyone wants to borrow that. I enjoy his videos, which is why I post them here. Take care and i'll post the next one soon.
By the way - I watched the video above and he says that the show was broadcast via webcam live - does anyone a recording of this?
