What I have is a copy of a download from some BT site that a friend gave me a few years ago. It's titled Sunshine Daydream by "Canis Major Productions" and is only 43 minutes of basically just the 1972 footage, there's none of the interviews or background material. I'm not sure what of the music is missing, it's been awhile since I've seen it and I didn't go through all of it. However, I still won't be forking out $55 for the new release, I'll wait until that can be downloaded.
It's dead and over when close enough is good enough.
