I don't believe the real date is December 2006, it seems more like October 2006. Anyways, yes these are very sweet little finds, and I am really glad new things are explored! But the big finds will be when at last all backstage videos Heshima used to upload will finally resurface
After research, I 've come to the conclusion that Amy DIDN'T like to speak and when she spoke, things rarely would end up on the internet. For example, there is an interview from Dionne at Q awards 2009 on youtube, and there isn't a single site that has at least audio from Amy's Q Awards 2009 interview.
There are "millions" of Glastonbury interviews both in 2007 and 2008, for really small artists, and there is not even a small audio snippet from Amy speaking there.
There are "millions" of different occasions where Amy is photographed singing or talking, but videos are vanished. E.g. her performance at Brit Awards 2004 nominations, her backstage tribute at Brit Awards 2007 before Noel Gallagher , etc.
What is more, she would send people instead of her like Mitch at most shows , and for example Dionne at Brit awards 2010 or 2011.
I still can't believe as well that she would turn up at places like Jazz after Dark before brits 2008 and people wouldnt upload stuff.
Needless to say, her company or MItch (I really can't blame Janis, she's a sweetheart) do not put out anything new. It's unbelieavable that even Kalkscheune was filmed, and nothing goes out there. It's unbelievable that Back to Black was remastered on its 360p version, though 4K versions exist for all frank music videos.
There is not much hope for her legacy to extend itself.
