The rivalry had been over a girl, of course. It had been brewing all year after Frank the French Horn player had insulted Pete the Percussionist in front of her, culminating in her leaving Pete for Frank 2 months later.

He waited until the third movement of the William Tell Overture and crushed Frank's skull with a circus tent-peg mallet.
