Called 'Follow The Music'
It's by Jac Holzman and includes Freddie Mercury in the book and tons of other artists. http://www.followthemusic.com/whobook.html
It seems like it'd be an interesting reading material, not just because of Queen, but all the music?
Here's some info on Queen on that site!! http://www.followthemusic.com/queen.html
"Please buy my upcoming album... I need the money"
