One thing I find interesting is in the theme song, you can clearly hear the voices of the Muppet Performers singing (definitely hear Frank in their), but the actual characters themselves in the inserts had their voices dubbed by the human castmembers.
Then again, I think Sonia participated in one of Jim's workshops when they needed more female performers, but she couldn't get the hang of it. As Frank always said, it's not as easy as it looks.
