So, I got this book last year around Christmas time. I absolutely love it. However, my friend recently borrowed it but hasn't been in touch to give it back. I'm going to a friend's house for a Christmas party tonight, and they were hoping I could bring my trumpet to play. But I really want this book back to play from... Since I own the book, would it be illegal to try and get someone who has the book to like, scan the Bb parts for me and email them? Anyone willing to do that for me?

This is the book I'm talking about, by the way.
