I downloaded it this week, and it is awesome.
It says on the iTunes page that there's a downloadable booklet if you download the whole album, which I did, but I can't figure out how to open the booklet. I downloaded it on my iPhone, if that matters.
I was amazed at certain songs sounding longer than I remember them (though I am aware that some songs were shortened in the original broadcast and extended in the 1980 ABC broadcast). I feel like the instrumental at the end of the "Brothers/Our World" reprise is longer than in the special.
I've read that The Jim Henson Company no longer has original backing tracks for The Muppet Show or Fraggle Rock, meaning audio releases would have to use the versions from the shows (if not re-using tracks that have already been released in audio form), so it is amazing that they've kept the original audio tracks for Emmett Otter after all these years, especially since it wasn't released as an album until now (were there plans for a soundtrack album back in 1977 or so?). Of course it's also amazing Henson kept all the deleted scenes from the original broadcast when it seems they didn't save deleted scenes from a lot of other productions.
