The more I think about this, the more I realize it’s going to be goofy in execution. There will be a noticeable delay in the responses, confusion, about 1/3 of the crowd participating, and it just isn’t practical…and this isn’t even factoring in the affect the first half result itself will have on the execution/“want to” from the crowd.
It’s going to sound like half-hearted gibberish. I’m actually pre-embarrassed for Drew with what this is going to be like. It’s hard enough to get 53 people to do this properly after practicing it multiple times, much less tens of thousands of people from all walks of life on a whim with a slight microphone audio delay.
