 How do you do that? It's like those great guitar players, man. They hear a song and they just start playing it. It's a gift. And it takes a lot of work. I mean, I used to volunteer at an old folks home. That's not a joke. Sang barbershop to them. So I got to talk to a lot of people with Alzheimer's and dementia. And so you can... It was an immersive experience. And I had no idea that all these years later it would pay off in order to help decipher the presidents of the United States.
