I saw this in London years ago...omg it really is a disaster AND I really love the music of Queen too.
It's not the music that's the mess - it is the book which is beyond horrible.
"The musical tells the story of a group of Bohemians who struggle to restore the free exchange of thought, fashion, and live music in a distant future where everyone dresses, thinks and acts the same. Musical instruments and composers are forbidden, and rock music is all but unknown."
