Watching the various news reports concerning Jim's death, I am surprised by the quality of some of the (I assume) Sam and Friends clips. The "That Old Black Magic" clip appears yellow instead of black and white, when all other times I've seen that clip it was clearly black and white, and there's a black and white clip of "Where Hunger Comes From", when the episode is known to exist in color. Considering only a handful of episodes were saved, I'd be surprised if there were multiple copies of the same episodes (I'd expect the Henson Company to have been the only company to have made copies). Of course, it was said in Jim Henson: The Biography that songs were included multiple times (and it's possible the same routines were repeated), so maybe they are from different episodes with the same segments (though it had been said that Jim only saved copies if there was a reason to, so I don't know why he would have saved multiple episodes with the same routines). Or maybe, considering some routines were done on multiple shows (and we know that Sam and Kermit did "That Old Black Magic" on Today), maybe some of those clips are from other appearances as opposed to Sam and Friends.
Last night I watched the restored Muppets: A Celebration of 30 Years, and it looks great. I can more clearly see certain characters that I had trouble seeing before (though it is still a little hard to see who all's there if I pause it). While I had noticed that some Muppets tended to move from spot to spot, I now notice that being a more common occurrence in the special than I previously did. And just now I noticed in the scene with Jim Henson you can see Statler and Waldorf way in the background. I noticed Leo and Grump from the Muppet Meeting Films who I had not noticed before (though I had spotted Grump in a publicity photo for the special) and I think Muppet Wiki listed the David Lazer Muppet as the only Meeting Films character to appear in the special.
