Song suggestions and poll

Behind a cut so arjache can avoid spoilers on my R&G writing. This danger has been averted.

Appropriate but incongruous song suggestions, please!

The context: in R&G Are Dead, a dumbshow rehearsal is interrupted by Hamlet and Ophelia running through doing the "To a nunnery" breakup scene. Ophelia is left crushed and sobbing on the stage.

That scene is being replaced in my version by a cabaret-themed montage scene. Appropriate influences:

• Ophelia interrupts the proceedings by coming on as the first murderess from Chicago (who opens the musical with an angry and manic All That Jazz, having just shot her lover and sister).
• The overall setting is the musical Cabaret.
• There will be elements of Moulin Rouge already in play, so something jarringly modern would be appropriate, if it can be spun into a torch song.

I request help from the hive mind in finding the best song to fit all these criteria. Please vote and or offer other suggestions! For all I know I am missing an entire category of appropriate songs.
