Kad said: ""Molasses to Rum" is one of the most scathing pieces of musical theatre to ever be written- a thorough indictment of our forefathers and their complicity in the slave trade, even those who championed freedom. Its power would not be diminished if it were sung by an actor of color. "
But would it not be strange to have an actor of color arguing in favor of the slave trade? There are many black actors who could do the song great justice, but would not be appropriate for the character in a fully realized production. If it were a concert production, where the emphasis is on the music and not on the book, I'd love to hear Brian Stokes Mitchell take a stab at it. In a fully stage production, it would be hard for me too buy the fact that an African American man would encourage slavery.
I will restate, the only time I find colorblind casting to be a bad idea is when issues of race play a key role in the show's plot. I have no problem seeing a black actor take on the role of Hamlet opposite an Asian Gertrude, which I have seen and really didn't think anything of it until I heard two older ladies talking about it after the show.
