My dad, an avid Pats fan who never missed a game, told me once he remembers hearing this on MNF. He's a backwoods, anti-everything John Lennon stood for, hard nosed conservative who still took notice when it happened, I guess if nothing else John Lennon made his mark on the world and at least got his message across weather you liked it or not. He certainly wont be forgotten.
I had just turned 1 when Lennon was shot so I don't remember it but for those that do here's the infamous MNF announcement.
