The Centennial High School Marching Knights swelled to more than 200 performers on Sept. 20 when nearly 100 middle school musicians sat in during the school’s homecoming football game. The eighth graders are students at Centennial feeder schools Haynes Bridge Middle School and Holcomb Bridge Middle School. The joint appearance Sept. 20 was not only an opportunity for the eighth graders to improve their playing skills, it also was an important recruiting tool for the high school band. The students will be performing together again, along with seventh graders, when the three schools present a cluster concert on Nov. 7 at 7 p.m. in the Centennial High School Auditorium.
