There was this really hefty book, 'La Rosalie and other love songs', by Saidah Rastam, that went into this super extensively. I think it was made possible thanks to a Khazanah grant, and formed the basis of a stage show. I wish it could become a regular sort of show, like annually - it was an enjoyable presentation. But the book is where it's at - hella heavy too, lol.
