From a cursory glance, I'd imagine these are the Blu-ray from the cancelled set that somehow found their way out the back door. But I don't have a copy in hand, so I'm just going by what people are saying about it.
Also...don't shoot the messenger, but, it seems it's disappeared again:

To be honest, if I can't obtain an original copy, I'll take a bootleg. I paid hundreds of pounds for damaged copies of Aqualung and Minstrel in the Gallery just to get my hands on the DVD-A discs and now they've been re-printed I could pick up either for about £35.
I only want the multichannel discs; they go into a CD wallet and everything else goes in a card board box and into storage.
When I posted to the forum to say how much I'd spent buying Aqualung people were horrified and a couple told me they could have just forwarded me the files.
I think it's a shame that this stuff isn't out there for people to listen to, if they want to, and that there are people on the forum who scour eBay to get whatever bootlegs that might pop up deleted; I think it's a bit mean-spirited.
