List of Celebrities Kermit Has Appeared With?

[Rattiemama]

Hi I'm new here, but actually found a way to do a speech assignment on Kermit the Frog. I've been looking for a list of famous people he has appeared with and have pieced together a lot of celebrity names from various sources, but wonder if anyone has a list of people Kermit has appeared with.

I am especially interested in political figures like former presidents, regents, and so on.

Thanks for any help in advance!
