80's endings
In the 80's they made a few different animated JHP logo endings that happend after Zoot blew his final note.
I somewhat agree to this:
"2) There was absolutely no chance that Disney - or anyone else - would have used the original clips, since they have ATV/ITC copyrights and logos superimposed over them."
However, since these are not going air on TV and they do not need to worry about time restriants, then they could always use the original footage THEN have the current coyright info and JHP logo shown.
OR
I would put out there that while Disney whouldn't be able to remove the ITV logo over Zoot, the copyright info below it could be covered over. I'd rather have 3/4 of the image then none at all and again like I said above the JHP logo could still come after that without the worry of time resraints.
I really don't get this whole mess. Many of the Muppet specials and Muppet Show episodes on file at the Museum of TV and Radio have the original ITV logo superimposed and even have the orginal ITV bumpers (which use to give be goose bumps, BTW cause that was how you knew The Mupet Show was about to begin!) Anyway these were given to the museum from JHC after they bought all the rights from ITV.
If they didn't bother to mess with the endings for the museum, and left them preserved, then they should be able to release them in the original way especially if they are touting it to be "completely restored" and the "Complete first Season".
