Colour-Blind Cabaret

My friend and I (I'm Black, she's Asian), are working on putting together our Senior Showcase, for our BFA in Musical Theatre program.

We've decided to work on a dual-project, in which we incorporate stereotypical Black/Asian roles in musical theatre pieces, and include some colour-blind casting in duets (I'm a tenor, she's a soprano/belt), etc.

Also, we're looking for songs concerning "racism/race issues/conflicts".

Any help would be great appreciated.
