Leo Catholic High School’s all-boys choir wowed AGT crowds, pushing through auditions to finals as a top-four act. The yearlong grind—secret auditions, cross-country travel, and relentless choreography—became a citywide story in Auburn Gresham, Chicago. Final performances, a buddy-buddy bonus with Aloe Blacc, and tributes from Chicago celebs gave the program national gravity. Hill’s retirement after 25 years, and the choir’s community-hugging run, created a fresh blueprint for school-brand momentum.
