Question about Hey Cinderella!

[The Count]

Greetings from the Count! By now I'm sure you guys are well acquainted with my Muppet Listings project. Well, I need a bit of help from someone well-versed with the JHC classic production of Hey Cinderella! This is the one version where the godmother can't turn the pumpkin into a coach till the last try and noone listens to Kermit as he gets excluded from the king's grace.

What I'd like to know is what are the names of Cinderella's two step-sisters? If you could, please provide the names of both of these characters and a descript to tell them apart. Please post your replies ASAP, since these are the only two characters missing from my listing to complete the inclusion of this special.
Thanks for your help and hope you have a happy holidays.
