*Mistoffelees sang a lot more than in current productions. His parts included the narration of the Gumbie Cat song and a few verses in Old Deuteronomy*
*Rumpelteazer doesn't always get away! In London she is mentioned by Demeter and Bombalurina as one of Macavity's henchcats*
*Demeter isn't the skittish cat she is later on. In the origional production, it is Mistoffelees' precognitive powers that alerts the tribe to Macavity's presence*
