‘”The most difficult thing to deal with was that there is approximately a two-second delay when you sing, so you really can’t listen to yourself (on the stadium’s public-address system). When you sing your fourth word, you hear your first word come out of the speakers and it’s in a different key, so if you listen to the playback, you’ll mess the whole thing up. And the Bills didn’t give you a chance to practice. They just handed you the microphone.”‘
