I had read about her casting earlier today, but on Playbill. The Playbill article has a video about the casting, and the fun part is seeing her reaction when she was told she got the part! I’ll post the link as others may enjoy watching. I have always loved Once on This Island, particularly the music. My D has played TiMoune and Little TiMoune (different productions).
