Mungojerrie and Rumpleteazer male cat: "...they were plausible fellows..." However, Rumpleteazer is usually portrayed as female in the musical. In the original Broadway production, the person cast as Rumpleteazer doubled as another character, Etcetera. In smaller local productions, this double character casting still occurs. In addition, Rumpleteazer and Mungojerrie can be cast to double as another tertiary set of characters: the twins Tantomile and Coricopat. Three distinct versions of the "Mungojerrie and Rumpleteazer" music exist: the original London production's version has a slower tempo and more jazz-like sound, while the more common original Broadway version is upbeat. Andrew Lloyd Webber wrote a new
Mungojerrie and Rumpleteazer setting of the song "Mungojerrie and Rumpleteazer" for the original Broadway production, in which the song was sung by Mr. Mistoffelees, while the actors playing Coricopat (Rene Clemente) and Etcetera (Christine Langner) danced the song as "dolls" made of junk, brought to life, and appearing out of the boot (trunk) of a car through the magic of Mr. Mistoffelees.
