Guest celebrities on "The Muppet Show", who also did Disney (part three)

My look at guest celebrities on The Muppet Show who also did some things for Disney continues. As always, I do not intend to do every single guest celebrity, only those whose Disney roles are in any way significant. The show's first season having concluded, I will now move on to the second season...

Season Two
The first episode of the second season has Don Knotts:

Knotts certainly has been in many Disney productions, mostly in the 1970s, including as Theodore Ogelive in The Apple Dumpling Gang and its sequel The Apple Dumpling Gang Rides Again...

...Wheely Applegate in Herbie Goes To Monte Carlo...

...Denver Kid in Hot Lead and Cold Feet...

...and, at the very end of his life, the voice of Mayor Turkey Lurkey in Chicken Little:

After that, there is Edgar Bergen:

Bergen and his dummies, Charlie McCarthy and Mortimer Snerd, have appeared in Fun and Fancy Free...

...as well as on the very first Disney television production, One Hour In Wonderland...

...and, very late in Bergen's life, they were on hand to pay homage to Mickey Mouse on his 50th birthday in 1978:

In addition, Charlie McCarthy was featured in animated form in two cartoon shorts with caricatures of movie stars. One was the Silly Symphony cartoon, Mother Goose Goes Hollywood...

...and the Donald Duck cartoon, The Autograph Hound:

Next up is Steve Martin:

Martin has had a long connection with Disney. One of his earliest jobs was working at the Main Street Magic Shop and learning comedy from Wally Boag of the Golden Horseshoe Revue. He also as one of the guest hosts in Fantasia 2000, introducing "Pines of Rome":

As part of Disneyland's 50th anniversary, Martin also hosted a film shown at the park to commemorate the occasion, sharing the spotlight with Donald Duck:

Up next after that is Madeline Kahn:

Although she has done very few things for Disney, she has done at least one significant thing, just before her untimely passing in 1999: providing the voice of Gypsy the gypsy moth of the Circus Bugs in A Bug's Life:

That's all for now. I will get to more later. Stay tuned.
