re: Jolson King of Clubs
I'm not sure one would want the kind of attention it would draw these days. I was just looking at v. 3, Rabbit and Dove magic, the modern rabbit production box, where he recommends producing a chicken and titling the effect "The Darkey's Dream". Thank goodness some things change even as others stay the same.
Under the category of effects I've not done, but have on the list is the Farmer and the Witch (also v. 3). I wonder if it mightn't help to pick for the witch a girl with conspicuous shoes to show at the bottom of the gown, if she and the boy could trade shoes as well. Either that, or to have the girl don a pair of, say, red overshoes onstage and then send her back with the costume mistress, etc etc.
