Crowd noise holds game up over 45 minutes.

I remember watching a 1969 Johnny Unitas led Baltimore Colts game that was held up by crowd noise. After a short while the delay became the important event of the game. I was with friends and a fair sized group of Colt’s fans at a forerunner of sports bars in Aberdeen, Maryland. We started cheering every time the fans started another game stopping roar.

Every now and then I research crowd noise and that 45 minute delay is never mentioned. Anybody here have any knowledge of that crowd delayed game?
