Bowdlerize: The scene where Ma is shafted by Gretchen Fox originally ended with her saying "I'd really appreciate it... If' you'd fall of the dock." after Gretchen was out of earshot. The DVD and most airings edit out the last part.
Breakaway Pop Hit: While the special has rarely been seen on TV since 2003 or so (though the Kermit-less version has seen DVD release in recent years), with Freeform (which at the time was still using the ABC Family name) being the first North American network since Canada's YTV to air it (albeit with Digital Destruction), the song "When The River Meets The Sea" is still fairly recognizable to those unfamiliar with the special itself (thanks to John Denver's version).
Digital Destruction: The version of the special that airs on Freeform as well as what was released on DVD in 2017 as the 40th anniversary edition mats the special to 16:9 (widescreen) despite it being filmed in 4:3 (full screen).
Edited for Syndication: The scene where Emmet and Alice go sliding was cut from the original ABC Family/Freeform airings. Later showings have reinstated it.
Executive Meddling: Due to Disney buying the Muppets, the Jim Henson Company had to edit out Kermit when they released the special on home video. The uncut version wasn't seen on television for years until itnote or a faux film-riddled version thereof was shown on Disney-owned ABC Family/Freeform as part of their annual holiday block, 25 Days of Christmas.
He Also Did: Russell and Lilian Hoban, the authors of the original book are perhaps better known for the "Frances the Badger" series of booksnote Whose titles usually took the form of "_ for Frances". Those who know Hoban best by his works aimed at adults or The Mouse and His Child are often startled to realize it's the same author.
Keep Circulating the Tapes: The only way to see the Kermit version since Disney bought the Muppets ..... until 2017, when a deal was finally worked out so Sony could release it on video; however Kermit's voice over narration was (still) edited out.
