High School Hero (1946)

The students at Anytown, USA High School (Monogram version) are down in the dumps: their football team faces almost-certain defeat, the school paper might need to suspend publication because the circulation is so low, and the principal intends to replace student performers at the school bazaar with professionals. But with the class roster on this Monogram campus made up of Freddie Stewart, June Preisser, Anne Rooney, et al, it's only a matter of about 45 more minutes before the team wins, the paper gets a large circulation boost, and all hands are on stage performing with the Freddie Slack and Jan Savitt orchestras.
