One day, a friend told me that if I liked Harry Potter, I absolutely had to watch the Very Potter Musical. (I actually linked to it a while ago on the blog, if you want to watch. I recommend it.)
Well, the Very Potter Musical is a fan musical, but it's certainly not the only musical that's been based on a books. There's, of course, the incredibly famous Wicked which is based, though not too closely, on a book of the same name. There is also Little Women: The Musical, which I have previously mentioned on the blog, not to mention a musical based on Jekyll and Hyde.
While many people have opinions on books becoming movies, most people don't consider the possibility that their book might become a musical.
I'm not sure how I'd take something like that. I'd certainly be flattered to have someone express that sort of interest in anything I wrote, but on the other hand, I'm not sure how I'd react to the changes the creators would doubtless have to make to suit the medium. Though, I won't lie, I'd be interested to see what kind of songs my characters would get.
How would you feel about someone turning your work into a musical? How do you feel about musicals (or, you know, straight up plays) based on books?
