It's too bad it doesn't say which compilation videos were shot that weekend, but at first I thought maybe it was Muppet Treasures, Muppet Weird Stuff, and Country Music. But then I noticed it said it was in 1984, and I've read that only the first four videos (as advertised in the promo) have a 1984 copyright (in the credits, not on the packaging), while all the others are copyrighted 1985 and all the videos were released in 1985.Here's one about the 1984 video compilations and the Play-Along Video series.
Though I guess maybe The Muppet Revue was shot first, perhaps as a pilot, and then the next three (Kermit and Piggy Story, Children's Songs and Stories, Rock Music) later on at the same time. Somehow I would have thought the first four would have been shot the same time. if it was a weekend, mayeb it'd make sense: Jim and Frank performed in the first two, which could have been shot one day, and the next two featured Jim and Richard, which could have been done the next day. The Kermit and Piggy Story and Children's Songs and Stories also could have been shot one day, as they didn't use big sets (a plain-colored background for both and a small set piece), while Rock Music with the Muppets used a much bigger and much more filled set.
But now I'm willing to bet The Kermit and Miss Piggy Story was shot on one day, when Frank was available, and then the next two the next day, since Richard Hunt was available for both videos, performing Scooter and Beaker.
Or maybe it was the last three (though I doubt it). I know that Jim and Frank performed in the wrap-arounds for all of the last three videos, and Richard was available for at least Fozzie's Muppet Scrapbook and Rowlf's Rhapsodies. Not sure if Dave Goelz performed in Fozzie's Muppet Scrapbook or Muppet Moments (I haven't seen FMS). And FMS and MM both took place in the attic and were hosted by Kermit and Fozzie (or was the Fozzie one just hosted by Fozzie, with Kermit featured in the same way as in Children's Songs and Stories?), so with the attic already set up and the performers available, those could have been shot back-to-back.
Regardless of all that speculation, it was good to finally see some acknowledgement of those videos by The Jim Henson Company, even if it did focus more on the Play-Along Videos (none of the photos had to do with the compilations... No copies of scripts showing examples of how the clips were listed, no publicity photos, no photos of video covers). Though if it was going to talk about the various Muppet videos, I wish it would have also spoke of the InteractiVision videos and the Muppet Babies Video Storybooks (we'll probably get something eventually), if not also the post-Jim Henson Muppet Sing-Along videos.
