Mapping between Madame's and Rocky Horror

[frobisherw]

So, Madame is obviously Frank-en-Furter. And Jedd is the creation. I think the rocker on the motorcycle is Perry. The aliens are the Utopian hostages (especially considering the ending of TWTB). The girl in the sparkly top hat is ... hm. Oh -- she's Heloise. Obviously. Given that the visitors (Brad & Janet) are Carlyle and Thisbe -- which is which? Considering which of the pair spends more time being "shocked, shocked" -- that implies Thisbe is Janet. Oh, and the Narrator is Mycroft, of course.

Further mappings?
