Jenny found this and sent me a DM.
"Otsego Public Schools, Van Andel Institute and singer Matt Giraud are teaming up to fight cancer with a “Community for a Cure” purple football game, 7 p.m. Oct. 15 at Otsego High School. Mr. Giraud will sing the national anthem before kickoff and then sign autographs. Football players and cheerleaders will wear purple to symbolize the fight against cancer. Proceeds benefit cancer research at Van Andel Institute."
