I can’t be sure (I’ll just have to double check by watching the DVD again, darn :D), but going from memory, you’re absolutely right. I had completely forgotten about that. It’s probably reasonable to infer that this was not an exception either…
But I still stand by the rest of my post… They made their money off movies, albums, merchandise and other promotional activities. 
Usually. Most often, they were just careful about how they wrote their scenes, so that two muppets voiced by a single actor just don’t interact that often. On The Muppet Show, Fozzie and Miss Piggy never interact for more than a line or two, and even then one is usually in the distance or something. It’s pretty striking, considering that they’re both such core characters, but they hardly ever seem to run into each other. And Rowlf sometimes says a line to Kermit, but then he’ll just walk offscreen.
No, it’s perfectly resonable to infer that this was an exception; it would have been a test audience.
It’s all community theater. Nobody gets paid to perform (except the orchestra), but Kermit is there to keep things under control and try to keep the standards up.
How does the owner of the theater get paid? Advertising in the programs. Grants. Donations. A show that can attract guest stars of that caliber must be generating a lot of public interest (I mean, c’mon! They actually booked Angus McGonagall the Gargling Gargoyle!).
Speaking as a veteran of community theater, it’s not as far fetched as you might imagine.
No, Fozzie wasn’t Bert in a bear suit.
Yoda in a bear suit, he was.
Naw. Grover was Yoda. Talk backward he did to trick Luke, who sharpest knife in the drawer was not.
Why do we always come here
I guess we’ll never know
It’s kind of like a torture
to have to watch the show
You’ve nailed that one, Marley. My humble impression of “lovable furry old Yoda” never fails to send my six year-old into giggle fits.
That was part of Steve Martin’s shtick.
On his Let’s Get Small album, he goes into how much the audience paid and the value of the show he’s doing.

Fozzie’s not a bear…he’s a wearin’ a necka tie!
ka-ching
That would be the worlds funniest joke, would it not?
