I saw "Heidi" on TV when I was a kid. That would have been around 1969. Maybe I saw the movie that pre-empted that game! Back then, I couldn't give two craps about football.
I watched the Heidi Bowl on TV. It was a nationally televised game featuring Broadway Joe. We were just kids, but I remember we were really pi##ed and stunned when the Heidi movie started before the game was over.
