Well, you picked the right month to start this thread, since her most famous voice role was on
"Emmet Otter". I always really liked her voice. Her singing was always beautiful sure, but she also has a great
speaking voice. She has this sort of great mother type voice that I always liked about her.
I think my favorite bit she did was the "Bumble Ardy" cartoon from Sesame Street:
Interesting thing about Marilyn: Like Richard Hunt and Fran Brill, she was originally hired by Jim as a puppeteer in 1970, working on
"The Great Santa Claus Switch", but after working on that special she decided she wasn't a very good puppeteer. So, because Jim needed more female voices, she ended up staying with the Muppets as a voice actor instead of puppeteer.
Y'know, I wonder what would've happened if she had continued puppeteering. She didn't think she was very good, but I don't think Fran or Richard were either, however they did improve a lot over time.
