Here's another thought developing from my previous idea:
If the films are Hollywoodized versions of the truth...
Perhaps: In true history it goes like this.
Kermit decides to go to an acting school. Along the way he meets Fozzie at the ElSleezo Cafe, Piggy at the beauty pagent, etc. They are chased by Doc Hopper who wants oto make Kermit his spokesperson, but eventually they get to the acting school asnd Miss Stacy won't let them in. They manage to get through to the man in charge, and he gives them a shcoolership for their acting studies.
(In terms of the Muppet Movie Mr Gag Beezly {Or whoever their writer is, [other than Jerry Jhul, of course]} decided it would be a better movie if they were heading to Hollywood instead of an acting school. It's called Dramatic licence, and they decided to do that to make it more exciting, etc... But it is still mostly based on real events...
Also, remeber that in Real Life the Muppet Show was a show, not a hollywood production, or even on TV)
Back to the True story:
They finish up at the acting school with a big production of Manhatten Melodies. They travel to Broadway, etc, etc... The Weding Is Just In the Play, but In The Real Play the Church is Built Differently and Gonzo Plays the Minister.
(In Mr Gag's Beezly's version for the movie to make it more dramatic at the end, he adds this questian of whether they were married [in the movie] and the answer is, yes. Kermit saying, "I thought Gonzo was playing the minister" is an 'in' joke for the Muppet Gang because in Real Life Gonzo did.)
Back to Real Life:
After the production of Manhatten Melodys they make The Muppet Show in a small town theatre owned by Scooter's Uncle. Scooter joins as he did in TMS.
They are so famous they decide to make movies of their life. They hire someone named Mr Gags Beezly (or whatever) to write the story, but more dramatic.
He does.
....
Now, I'll try and add the rest of Muppet history later.
