the book was great - I liked it better than the musical (don't scream - I did like the musical just not as much as the book). The book was a little less cliche and didn't feel the need to tie into the Wizard of Oz so cleanly, I thought. They are different media so I think they were ok to musicalize (yes, that is my new technical term) it as they did... I still preferred the book.
I sing for myself. I sing when I want, whenever I want to, just for me. I sing for my own pleasure. Do you understand that?
