Book excerpt: Without music, the world is just blah. That’s my take on life, anyway. Mum says rock is the only music worth listening to, but I think everyone should find their own beat. When I hear that Principal Keiren plans to cut all of the arts classes at Watterson Primary, there's no way me and my new mate Flynn are gonna let that happen. We're dragging our secret Broadway appreciation society into the spotlight. It's time for Watterson: The Musical!
